How To Add Custom Dictionary in Outlook?

Last Updated on September 5, 2023 by Amit Bansal

A dictionary is a collection of words that are known or are known to exist in one’s language. A dictionary is a useful tool for anyone learning a language and for students studying a foreign language.

Look up a word on Outlook and suddenly you have a new dictionary installed for that word. Usually, this happens when a word is misspelled, for example.

A good spell checker can do wonders, but if you use Microsoft Office, Outlook is smart enough to also suggest alternative spellings, words that mean the same thing, or words that are like “the” searched word.

Most of the words still have meaning likely in the different forms of English but do not exist in the Dictionary. In such a scenario, you can add or create your customized dictionary.

Normally when you type a special name/word in an email message, for instance, the mailsmartly in Outlook, it will flag the spelling mistake of mailsmartly with the wavy red line.

How To Create and Add Your Own Custom Dictionary in Outlook?

Creating your own custom dictionary is not as simple as that, it’s a process of importing your existing dictionary which you already have on your computer system.

A custom dictionary may be necessary if you want to add multiple words to a Microsoft Outlook application. This tutorial provides the steps needed to create and include a custom dictionary.

Importing a dictionary (.dic) file is important:

Let’s begin with how to create a (.dic) file that consists of multiple words.

  • Open Notepad or any other text editor from your computer.
  • Type words one word per line.
  • Once your list is ready, save the file with a .dic extension for instance:(mycustomdictionary.dic)

Now it’s time to upload the file:

  • Click File >> Options in Outlook
  • Click on the Mail option from the left navigation section.
  • Click Spelling and Autocorrect >> Custom Dictionaries
  • From the Custom Dictionaries dialog box, click the Add button.
  • Choose the .dic file from the browser or select the location where you save your above file.
  • Click Ok to finalize.

Importing and Exporting Dictionaries

Importing Dictionaries

To import a dictionary in Outlook, follow these simple steps:

  1. Go to File > Options > Mail > Spelling and Autocorrect > Proofing.
  2. Click on Custom Dictionaries.
  3. Click on the Add button.
  4. Navigate to the location of the custom dictionary file (usually with a .dic extension) that you want to import.
  5. Select the dictionary file and click Open. The custom dictionary will be added to your Outlook dictionary list.

When you import a dictionary, Outlook will recognize the words in the custom dictionary alongside the words in the default dictionary.

This allows you to use both sets of words when using spell check and autocorrect functions.

Exporting Dictionaries

To export a custom dictionary, you can follow a similar process:

  1. Locate the custom dictionary file on your computer. The default location for the custom dictionary files in Outlook is C:\Users\%Username%\AppData\Roaming\Microsoft\Uproof\Custom.dic.
  2. Copy the custom dictionary file (.dic) you want to export.
  3. Save the copied file in your desired location, such as an external drive or cloud storage folder.

By exporting your custom dictionary, you can easily transfer it to another computer or share it with others.

Just make sure to follow the steps in the Importing Dictionaries sub-section to add the exported dictionary to the new Outlook installation.

Final Words

So, take advantage of this feature and unleash the full potential of Outlook by incorporating a custom dictionary.
