how to block or Unblock an email on Outlook?

Last Updated on February 26, 2024 by Amit Bansal

Recently, I faced an issue where I couldn’t receive an important email in my Outlook inbox. Upon investigation, I found that my inbox had reached its limit due to an influx of spam emails that were of no interest to me.

Unwanted emails not only clutter the inbox but also lead to frequent notifications, which can be disruptive during crucial tasks like presentations.

Often, these emails result from unnecessary subscriptions or sharing my email address with various individuals or websites.

It’s essential to tackle these issues for better email management and a smoother experience.

In this article, you will learn step by step tutorial on “How to block and Unblock email addresses and Domain in Outlook“.

Blocking Emails on Outlook

Once you subscribe to unnecessary websites, or somehow you don’t need anymore, the “Unsubscribe” feature just isn’t enough to delete spam. Here you can block or restrict unwanted email/s in your inbox.

Block an Email Address

To block specific email addresses in Outlook, we first have to access our inbox. Right-click on an unwanted email and select “Junk,” followed by “Block Sender.”

Alternatively, we can click on “Junk” on the Home tab of the ribbon and select “Block Sender” from there.

Clicking on “Block Sender” prompts a final confirmation from Outlook, and clicking the “OK” button on the message popup completes the process.

These steps apply to all versions of Outlook, including 2013, 2016, 2019, and Outlook 365 Classic.

Important Note: If you are using the new Outlook, the steps to block a sender are almost similar to those in classic Outlook. I have also shared an image to help clarify the process.

Block Multiple Email Addresses

If you want to block multiple email addresses in Outlook, start by selecting the messages you wish to block in our inbox.

Next, click the three dots (More options) at the top toolbar. From the menu, select “Block” under “Move & delete.”

A confirmation popup window will appear, and we’ll need to click “OK” to complete the process.

Block Domains

Sometimes, it’s more efficient to block entire domains rather than specific email addresses.

To do this, go to “Settings” within Outlook, and then click on “Mail.”

From there, scroll down to the “Junk email” section and click on “Blocked senders and domains.”

Click “Add” and enter the domain we want to block, such as “example.com.”

Rules for Blocking Unwanted Emails

Outlook allows us to create rules for handling unwanted emails effectively. To create a rule, go to “Settings,” click “Mail,” and then navigate to “Rules.”

Click “Add new rule,” and create a custom rule that suits our needs, such as sending emails from a specific sender directly to the Junk Email folder.

In summary, blocking emails in Outlook can be done by blocking specific email addresses, multiple email addresses, entire domains, or by applying rules.

By using these methods, we can efficiently manage our inboxes and filter out unwanted messages.

How to Create a Block List

Outlook provides a smart feature that enables users to create a block list using names, email addresses, or entire domains.

Let’s explore in detail how you can create a block list in both Outlook Classic and the new Outlook.

Let’s start with Outlook Classic.

First, click on the “Home” tab, and from the “Delete” section, select “Junk.” This will display a few options. From the dropdown menu, select the last option, “Junk E-mail Options.”

Create Block List

This action will open the “Junk Email Options” dialog box. From the options available, select the “Blocked Senders” tab.

Click “Add.” In the box labeled “Enter an e-mail address or Internet domain name to be added to the list,” enter the name or address you want to add. You can enter it according to the following pattern:

  1. Someone@domain.com
  2. @domain.com
  3. domain.com

Finally, click “OK.” The email address or domain will be immediately moved to the Junk Email folder. If you have multiple email addresses or domains to block, repeat the process. You can then observe the list of blocked email addresses.

Let’s check out with NEW Outlook.

The new Outlook interface has been introduced, which closely resembles Outlook on the web.

If you want to create a block list in the new Outlook, the outcome is quite similar to that in the classic version of Outlook.

However, the steps to achieve this are slightly different. Let’s dive in and understand the process.

To create a block list in the new Outlook, follow these steps:

  1. Open the new Outlook and go to the top right corner of your screen. You will see a gear symbol, which represents settings. Click on it.
  1. You will be directed to the settings dialogue box, which consists of three sections. From the first section, click on “Mail.”
  2. From the second section, click on “Junk email.”
  3. In the third section, you will see several options. Look for the “Blocked senders and domains” section at the top.
  1. Click on the “Add” button and enter the email address you want to block. Press Enter to add that email below the list. Repeat this process for each email address you wish to add to the block list.

By following these steps, you can easily add email addresses to your block list in the NEW Outlook.

Note: If you are a regular user of Outlook on the web, you can follow these steps to add a block list in the new Outlook.

Create Block List Using Import from File

In the examples above, you can add multiple email addresses or domains to block them from your inbox.

However, entering email addresses individually can be a time-consuming process.

Fortunately, Outlook’s “import from file” feature allows users to directly import all their corporate addresses into the block list instantly with a single click.

In the Junk Email Options popup, click on “Import from file.” Select the text file containing the list of email addresses and domains you want to block (Outlook only allows uploading of text files).

Once you select the text file and click “Open,” all your addresses will be automatically added to the blocked sender list. Click “OK” to complete the process.

If you need to add any other email addresses, go to the blocked sender list and repeat the process. You can also edit or remove any address or domain according to your requirements.

Block email addresses from different countries/regions in Outlook

You may find unwanted email messages come from other countries/regions too. Outlook allows you to block certain email messages from those areas.

Although the above process can also help to block those emails, Outlook blocks messages from email addresses that end in a particular top-level domain or country/region code.

  • Click Home Tab >> Click Junk from the delete section >> then click Junk E-mail Options
  • Select the International tab >> click Blocked Top-Level Domain List

The Blocked Top-Level Domains List lets you block messages that come from email addresses ending with a specific country code AF (Afghanistan), IN (India), or AU (Australia), there are numerous countries, that you can block by simply selecting the checkbox.

Tips for Handling Unwanted Emails in Outlook

Handling unwanted emails in Outlook can be a challenge, but there are several effective strategies you can use to manage them more efficiently.

Here are some tips for handling unwanted emails:

  • Mark as Spam: Use the spam or junk email feature in Outlook to mark unwanted emails as spam. This helps train the spam filters and sends future similar emails directly to the spam folder.
  • Unsubscribe: If you receive unwanted emails from legitimate senders, look for the unsubscribe link usually found at the bottom of the email. Clicking on it should remove you from their mailing list.
  • Set up Filters/Rules: Utilize Outlook’s filtering or rules feature to automatically move unwanted emails to specific folders or delete them. You can create rules based on sender, subject, or other criteria to better organize your inbox.
  • Block Senders: As discussed in the previous section, block email addresses or domains from which you consistently receive unwanted emails. This prevents those senders from reaching your inbox.
  • Use the Sweep Feature: Outlook’s Sweep feature allows you to quickly clean up your inbox by deleting or moving unwanted emails from a specific sender. You can choose to delete all emails from that sender or keep only the latest one.
  • Report Phishing Attempts: If you receive suspicious emails attempting to steal your personal information, report them as phishing attempts. Outlook has built-in tools to report phishing emails, helping to protect yourself and others.
  • Manage Notifications: Adjust your notification settings to minimize interruptions from unwanted emails. Customize your email alerts to only receive notifications for important emails or set specific quiet hours to avoid disturbances during specific times.
  • Regularly Review and Clean Up: Take the time to review and clean up your inbox regularly. Delete unnecessary emails, unsubscribe from mailing lists you no longer wish to be part of, and keep your inbox organized and clutter-free.
  • Use Email Filters: Configure email filters to automatically sort incoming messages into specific folders based on criteria such as sender, subject, or keywords. This helps keep your inbox organized and separates unwanted emails from important ones.
  • Be Cautious with Email Sharing: Exercise caution when sharing your email address online. Be mindful of where you provide your email address and consider using a separate email address for sign-ups, subscriptions, and online forms to avoid spam.

By implementing these tips, you can better manage and reduce the impact of unwanted emails in your Outlook inbox, improving your overall email experience and productivity.

Remember to regularly review and adjust your strategies based on your changing needs and preferences.
