Office 365 - Thunderbird (Mac) - Exporting Personal Dictionary

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result. Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?

Exporting Thunderbird Personal Dictionary

Close Thunderbird before beginning the following steps.

1. Open the Finder application.

   

2. Press Shift-Command-G to open the Go to Folder window. (If you are using a Windows keyboard use the "Windows" key in place of the "Command" key.)

3. Type the following into the window: ~Library/Thunderbird/Profiles/

   Select Go to proceed.

   

4. A window will open with your Thunderbird profile folder. Open the folder.

   

5. Navigate to the "persdict.dat" file. Copy and Paste it to your Desktop.

   

6. Using a text editor (like TextEdit), open the "persdict.dat" file saved on your Desktop. You will see your list of custom dictionary words.

7. In your new email client begin drafting a new message. Copy and Paste your word list from TextEdit. Run the spellchecker and add the words to your new email client's custom dictionary.
