Outlook Categories vs Folders: A Clear Comparison for Efficient Email Organization

Last Updated on August 20, 2023 by Amit Bansal

Microsoft Outlook is a widely-used email client that offers various features to help users manage their emails efficiently.

One such feature is organizing emails using categories and folders. While both methods serve the purpose of organizing your emails, understanding their differences can contribute to a more effective email management system.

Outlook folders function similarly to the file folders on your computer, allowing you to group and store emails in designated locations.

On the other hand, categories provide a visual organization tool using color codes, making it easy to identify emails based on specific groupings.

By leveraging both categories and folders, users can create a structured and visually appealing inbox that simplifies email management.

Understanding Outlook Categories vs Folders

Outlook offers two main ways to organize emails: folders and categories. Both these features help users manage and organize their inboxes effectively.

Understanding the difference between Outlook folders and categories can assist users in keeping their email experience streamlined and efficient.

Outlook folders function similarly to typical file folders found in document systems.

Users can create folders for specific projects, clients, or subjects, and then move emails associated with those topics into the corresponding folder.

This method aids in maintaining a well-structured Inbox, where emails are stored in dedicated folders according to their content or purpose.

On the other hand, Outlook categories operate on a more flexible and versatile system that uses color-coded tags to label emails.

Users can assign multiple categories to an email, enhancing the ability to find and group related emails quickly.

By default, categories are labeled by color (e.g., “blue category,” “green category“), but users can customize these into more descriptive names to match their workflow.

One significant advantage of using categories over folders in Outlook is the compatibility with Outlook’s rule feature.

Rules for auto-filing incoming mail work more efficiently with categories, as they do not move the email away from the Inbox, allowing the user to read it before taking further actions.

This feature works seamlessly with Outlook’s search function, enabling users to locate categorized emails easily and promptly.

While both folders and categories have their unique benefits, users may choose to utilize a combination of these features to maximize their email organization.

Some may prefer the clear structure and separation provided by folders, while others may find the flexibility and adaptability of categories more suitable to their needs.

Ultimately, understanding the differences between Outlook folders and categories can empower users to make informed decisions regarding their email organization system.

Exploring the Basics of Outlook Folders

Default Folders in Outlook

Outlook comes with several default folders to help users organize their emails. These include the Inbox, Sent Items, Deleted Items, Drafts, and Junk Email folders.

Each folder serves a specific purpose and helps users manage their email effectively.

Creating and Deleting Folders

Creating a new folder in Outlook is simple. Click on the “Folder” tab in the Ribbon, then click the “New Folder” icon.

This will open the “Create New Folder” dialog box, where you can enter the folder’s name and select its location.

Once you’ve completed these steps, click “OK” to create the new folder.

Deleting a folder is just as easy. Right-click on the folder you wish to delete, and then select “Delete Folder” from the context menu.

Keep in mind that when you delete a folder, all the emails it contains will be moved to the Deleted Items folder.

Renaming Folders

To rename a folder, simply right-click on it and choose “Rename Folder” from the context menu. Type the new name for the folder and press “Enter” to save your changes.

Navigating Through the Folders

Navigating through Outlook folders is uncomplicated. Users can simply click on a folder in the Folder pane to view its contents.

To move emails between folders, simply drag and drop the email into the desired folder. This email organization method aids in keeping your inbox clutter-free.

Inbox Management Using Folders

Outlook’s folder structure plays a significant role in inbox management.

By creating custom folders and arranging emails according to categories or priorities, users can ensure that important emails don’t get lost among less important ones.

Additionally, setting up Outlook rules helps to automatically move incoming emails to appropriate folders, streamlining the inbox management process.

Overall, the effective use of folders is crucial for maintaining a well-organized and efficient email experience in Outlook.

An Overview of Outlook Categories

Outlook categories provide a different way to organize and manage your emails, rather than using folders.

By assigning categories, you can easily filter, search, and group emails based on your specific criteria.

Understanding Category Colors

Outlook categories are represented by color tags, allowing you to visually distinguish messages in your inbox.

You can assign colors for different categories that match your preferences, making it easier to recognize the grouped emails at a glance.

Organizing by Category

Instead of moving emails into numerous folders, categories make it easier to manage your inbox.

You can assign multiple categories to a single email, letting you see it in various contexts without having to duplicate it.

When searching or filtering your inbox, you can choose to display emails based on their assigned categories.

Renaming Categories

By default, Outlook provides generic names for each category (like “blue category” or “green category”).

To customize category names according to your needs, access the Outlook settings and rename them.

For example, you could name a category “Work” or “Personal,” enabling you to identify the purpose instantly.

Assigning and Removing Categories

To assign a category to an email, select the message and apply the desired category from the menu.

You can assign multiple categories to a single email, providing an easy way to group messages related to different aspects of your work or life.

To remove a category from an email, simply deselect the category tag in the same menu.

Using Outlook categories can save time in managing your inbox, enabling efficient organization and effortless management of your emails.

Using Tags and Labels in Outlook

Outlook offers a versatile way of organizing emails through the use of categories, which can also be considered tags or labels.

These categories offer more flexibility compared to the traditional folder system, as multiple categories can be applied to a single email message.

Categories can be found at the top of the Outlook application and can be used in both the desktop version and Outlook Web App (OWA).

By default, Outlook provides some pre-established categories, but users are free to create customized categories that cater to their specific needs.

One of the benefits of using categories over folders is that categories allow users to tag and label messages without moving them into separate folders.

This ensures that the emails remain in the Inbox, making them easily accessible for reading and further actions.

When a user is done with an email, it can be simply moved to a single folder, and because of the assigned categories, all emails can still be easily organized and located.

To view emails according to their assigned categories in Outlook, users can enable the Group by Category view.

This feature can help users easily manage mountains of mail by sorting and displaying emails based on the assigned categories’.

This method provides a clear and organized view of various email messages, making it easier to find and identify important emails.

In summary, using tags and labels in Outlook through the category system can make email organization more efficient and effective, compared to the traditional folder-based approach.

It offers more flexibility without compromising the convenience of accessing and managing emails, making it a valuable feature for Outlook users.

Employing Search Functions in Outlook

Outlook offers two primary methods to organize and find email messages efficiently: categories and folders.

Utilizing the search function alongside these organizational tools allows users to locate specific email messages quickly.

Categories provide a flexible method of labeling email messages with different colors and tags, making them easily identifiable.

Users can create custom categories to suit their preferences. To set up categories, navigate to the ‘Home’ tab, click ‘Categorize’, and select ‘All Categories…’

Search functions can be employed to find email messages that belong to specific categories.

Folders, on the other hand, enable users to physically separate email messages into distinct directories.

To use the search function within folders, select the folder, and use the search bar at the top of the Outlook window.

This process narrows down the search to the contents of that particular folder.

For a more targeted search, Outlook offers Instant Search, allowing users to find relevant email messages by using specific keywords or applying search filters.

Additionally, Outlook provides an option to create tailor-made search folders. To do this, right-click on the ‘Search Folders’ option, then select ‘New Search Folder’.

Choose a pre-configured search folder or create a custom search folder.

Employing the search function in combination with categories or folders empowers users to maintain organized inboxes and efficiently locate email messages.

Knowledgeable use of these tools in Outlook enhances productivity and ensures clarity in email management.

Comprehending Email and Contact Management in Outlook

Sorting Emails

In Microsoft Outlook, sorting emails can greatly improve email inbox organization. Users can sort their messages by various criteria, such as sender, date received, or size.

This can help users quickly locate specific emails and keep their inbox uncluttered.

Users can also apply categories to further differentiate emails based on various projects, clients, or other criteria, making it simple to find messages related to a certain project, for example. 

This article provides a detailed comparison between using folders and categories in Outlook to manage email organization.

Filtering Contacts

Filtering contacts in Outlook allows users to manage and organize their contacts more effectively.

Users can sort their contacts based on various factors like the company, job title, or tags.

By applying filters, users can quickly access a specific group of contacts for efficient communication.

To manage contacts in Outlook, users can follow the steps provided in the Microsoft Support article.

Color Coding Contacts

In addition to sorting and filtering, Outlook allows users to color-code their contacts.

This can be done by assigning categories to contacts, which can be customized with unique color codes.

Color coding makes it easier to visually distinguish different contact groups, streamlining communication and organization.

Users can also use quick steps to apply categories and color codes to contacts and email messages with only a few clicks.

Automatic Sorting and Filtering

Outlook provides automation features such as rules that can be applied to incoming emails to automatically sort, filter, or organize messages based on user-defined criteria.

These features save time and enhance the user’s efficiency in managing their inbox.

By using Outlook’s built-in tools and features, users can ensure their email organization, contact management, and communication effectiveness are optimized. 

This blog provides valuable insights on using categories in Outlook to enhance email organization and automation capabilities.

Outlook Task Features

Tasks and To-Do List

Outlook provides a robust task management system, which allows users to create and organize tasks efficiently.

Users can create tasks by clicking the “New Task” button, and each task can have attributes such as due date, priority, and categories.

Tasks can be organized in the Task list, which displays all tasks, including flagged email messages, providing a consolidated view to help users stay focused on their priorities.

Using Views to Organize Tasks

Aside from the default views, Outlook allows users to customize their views to better organize and filter tasks.

By adjusting the view settings, users can sort tasks by different criteria, such as due date, category, or priority.

This feature enables users to quickly focus on specific tasks and efficiently manage their workload.

Email to Task Conversion

A convenient feature in Outlook is the ability to convert emails into tasks. By flagging an email, it automatically adds the email to the Task list, providing an easy way to create and track tasks without leaving the inbox.

This feature streamlines the process of managing tasks and ensures that important emails are not forgotten.

Through the use of tasks, views, and email-to-task conversion, Outlook provides a powerful task management system that helps users stay organized and efficient in managing their work and personal lives.

Outlook’s User Interface Elements

Outlook offers its users a friendly and intuitive interface, making it easy to navigate and organize emails. This section focuses on three main elements: Navigation Pane, Reading Pane, and To-Do Bar.

Navigation Pane

The Navigation Pane in Outlook is a powerful tool that helps users manage their emails, calendar events, and tasks.

Located on the left side of the window, this pane displays a list of folders and categories, allowing users to easily access their Inbox, Sent Items, Deleted Items, and more.

Users can also create custom folders and categories, further enhancing their email organization.

Account management options like adding, editing, or removing accounts can be done through the Navigation Pane as well.

Reading Pane

Outlook’s Reading Pane, located on the right side or bottom of the window (depending on the user’s preference), allows users to conveniently view the contents of an email without opening it in a separate window.

This feature helps save time and effort when browsing through emails, as users can quickly read and skip through them.

Emails displayed in the Reading Pane can also be categorized, marked as read or unread, and moved to different folders to keep their Inbox organized.

To-Do Bar

The To-Do Bar in Outlook is a useful addition that helps users keep track of their tasks and appointments.

Positioned on the right side of the window, this feature displays a snapshot of the user’s calendar, upcoming events, and task list.

Users can easily add new tasks and appointments directly from the To-Do Bar, and it also provides quick access to their calendars and contacts.

This feature ensures that users won’t miss important deadlines or events by keeping reminders easily visible within Outlook’s main window.

Dealing with Outlook’s Email Limitations

Microsoft 365’s Outlook email client has some limitations when it comes to organizing and managing emails.

Users often deal with these limitations by using folders or categories to help them store their emails.

Both folders and categories are useful tools that can be used in different ways to suit your needs.

Folders in Outlook work just like physical folders, allowing you to organize your emails in a hierarchical structure.

This is useful for users who want to keep their inboxes clean and organized.

However, folders can be limiting when it comes to searching for specific messages or organizing emails that belong to multiple categories.

Categories, on the other hand, are more flexible and can be applied to emails so that they can be organized and searched more efficiently.

Users can apply multiple categories to a single email, which can be helpful when a message is relevant to multiple topics or projects.

With categories, an email can stay in the inbox while still being organized, making it easier to track and manage.

You can learn more about setting up Outlook categories from this step-by-step article.

Limitations in Outlook’s email management can also be a concern for users utilizing POP and IMAP protocols.

POP (Post Office Protocol) downloads emails to your computer and removes them from the email server, while IMAP (Internet Message Access Protocol) keeps them on the server and synchronizes them across devices.

Since Microsoft 365 uses Exchange, it is designed for better integration with Outlook.

However, users with POP or IMAP email accounts may still experience limitations when working with Outlook’s folders and categories.

Email storage in Outlook has a limit, which can be an issue for those who need to store a large number of emails.

To avoid reaching the maximum size, users should regularly manage their mailbox, deleting old emails and maintaining a clean inbox when possible.

Also, it is good practice to keep an eye on the size of your folders. You can check the folder size by right-clicking the email address in the left pane and then choosing “Data File Properties,” followed by selecting the “Folder Size” button.

In summary, dealing with Outlook’s limitations involves using folders or categories effectively to store and search for emails, as well as managing the mailbox size to avoid reaching the limit.

Depending on your needs, you can choose the best approach for you, whether it is using folders, categories, or a combination of both.

Advanced Outlook Features

Focused Inbox

In Outlook, the Focused Inbox feature helps users prioritize their email messages by automatically categorizing them into two tabs: Focused and Other.

The Focused tab showcases important emails that require immediate attention, while the Other tab contains less important messages.

This feature allows users to efficiently manage their inboxes and stay on top of critical tasks.

Place Holders

Outlook uses Place Holders to temporarily store attachments in emails, reducing the mailbox size and improving email performance.

When an attachment is opened, it is downloaded and stored in a temporary folder on the user’s local device.

This enables users to access attachments without needing to download them multiple times, and it also helps keep their email storage organized and clutter-free.

Archiving and Deleting Items

Outlook offers two ways to manage old or unnecessary email items: Archiving and Deleting.

  • Archiving: When users archive an email, it is moved from their inbox to a separate folder called the Archive. This helps keep the user’s main inbox organized while still allowing them to access archived emails if needed. Archiving can be done manually or automatically through the use of Outlook’s Auto Archive feature.
  • Deleting: Deleting an email in Outlook moves it to the Deleted Items or Trash folder. This folder stores deleted items temporarily, allowing users to recover them if needed. However, items in the Deleted Items or Trash folder can be permanently removed by emptying the folder or setting up automatic deletion rules.

Both archiving and deleting are crucial methods for maintaining a well-organized and efficient Outlook inbox.

By utilizing these features, users can effectively manage and declutter their email storage, leading to increased productivity and focus on essential tasks.

Efficiency Measures in Outlook

Achieving Inbox Zero

Inbox Zero is a concept that aims to keep your email inbox clean and clutter-free. To achieve this in Outlook, you can use a combination of folders and categories. 

Organizing Email in Outlook: Folders vs Categories explains that folders are used to store your emails, while categories can visually organize emails in your inbox using color codes.

This combination helps you easily locate and sort your emails, streamlining the process of Inbox Zero.

Automation and Organized Inbox

One way to maintain an organized inbox in Outlook is by using Quick Steps and Rules for automation.

Quick Steps allow you to perform multiple actions on an email with just one click, such as moving an email to a specific folder or categorizing it.

Rules, on the other hand, allow you to set conditions for specific email actions, such as moving emails from a particular sender to a designated folder automatically. 

Microsoft Support provides several best practices for using Rules to keep your inbox organized and efficient.

Use of Rules for Email Management

Rules in Outlook play a vital role in email management. They help you automate routine tasks and organize your inbox efficiently. Some key benefits of using Rules are:

  • Filtering emails based on specific criteria – such as the sender, recipients, or subject.
  • Categorizing incoming emails makes it easier to visually sort and find messages in your inbox.
  • Organizing emails into folders, helps you maintain a clear inbox.

To set up Rules in Outlook, you can follow the instructions provided by Microsoft Support.

By utilizing Rules effectively, you can improve your email management, save time and effort, and maintain a more organized and efficient inbox.

Role of Outlook in Work Environment

Microsoft Outlook plays a crucial role in today’s work environment, serving as a comprehensive email and personal information management tool.

Part of the Microsoft 365 suite, Outlook integrates seamlessly with various other Microsoft applications, enhancing productivity for individuals and teams.

In the professional world, work email is the primary means of communication between colleagues, partners, and clients. Outlook provides advanced features that enable users to efficiently manage, organize, and prioritize their messages.

With the capability to create different folders and categories, users can easily sort their emails based on project, team, or priority, streamlining the process of accessing vital information.

Outlook not only simplifies email management but also offers calendaring, task management, and contact management functions.

Users can schedule meetings, set reminders, create and delegate tasks, and maintain a comprehensive database of contacts—all within one application.

This allows professionals to keep track of their commitments and ensures smooth collaboration with team members.

Another benefit of using Outlook is its compatibility with mobile devices, making it accessible through Microsoft 365’s cloud-based services.

This means users can access their emails, calendars, and contacts from anywhere, at any time, ensuring a seamless work experience.

In summary, Microsoft Outlook is an integral part of a modern work environment, facilitating efficient communication and organization for businesses of all sizes.

Its variety of features, integration with other Microsoft applications, and cloud-based accessibility make it a powerful tool for today’s professionals.

Projects and Outlook

Organizing projects in Outlook can greatly enhance productivity and efficiency.

Two elements in Outlook, categories and folders, can be utilized to manage project communication and ongoing tasks.

In order to choose the most suitable approach, it’s important to understand their respective functionalities.

Categories offer a versatile method for classifying emails. They enable users to apply multiple colors and labels to the same message, simplifying the sorting and identification process.

By default, categories are labeled by color, such as “blue category” or “green category.” However, users can customize these to align with specific project names or task types.

On the other hand, folders serve as dedicated areas for storing and organizing related emails.

Users can create separate project-based folders, to which incoming and outgoing messages can be sorted via Rules, a feature in Outlook.

Additionally, users can easily access and view entire email chains that pertain to a project.

When organizing projects in Outlook, users may utilize a blend of categories and folders to optimize their workflow.

Categories are ideal for quickly and visually grouping emails, while folders provide a way to organize project-specific emails in a structured manner.

Both elements can be utilized to manage task assignments, deadlines, and any other project-related communication.

By choosing the most suitable method or combination, project management in Outlook can become a streamlined and efficient process.


Organizing emails in Outlook can be achieved using two main methods: folders and categories.

Both options have their own advantages and can be used according to an individual’s preferences and organizational needs.

Folders are a traditional way of organizing emails, allowing users to create hierarchies for their messages.

To create folders, simply click the ‘Folder tab’, then the ‘New Folder icon’, and type the name of the new folder in the ‘Name field’.

People who prefer a more structured approach or classification might find folders more suitable.

On the other hand, categories provide a more flexible way of organizing emails. They allow users to assign multiple categories to a single email, enhancing the search and filtering capabilities.

This makes categories a great choice for those who like to maintain a fluid organizational system.

In conclusion, it is important to consider one’s personal preferences and organizational needs when opting for either folders or categories in Outlook.

While folders provide a structured approach, categories offer flexibility, making both options valuable tools for managing emails efficiently.
