Hello FrancesFollin-1068
I tested this scenario in my own environment and was able to reproduce a similar issue. In my case, it appeared to be related to an account conflict, although I initially thought I had signed in and activated Office, the account was not properly authenticated.
As a first step, please ensure that your Office apps are updated to the latest version and check whether the issue persists.
If the problem continues, kindly try the following:
- Close all Office applications.
- Reopen Microsoft Word and check whether a Sign in icon appears in the top-right corner prompting you to sign in.
- If prompted, please sign in using your work account, then reopen the affected document to see whether the missing options reappear and can be switched as expected.

If the issue still cannot be resolved, I recommend verifying that all important documents are backed up before proceeding with the steps below.
You may then follow Microsoft’s official guidance to remove old or potentially corrupted Office license files on macOS: How to remove Office license files on a Mac - Microsoft Support
Note: The following step removes Outlook profiles. If you have local data in Outlook, please ensure they backup this data before proceeding.
Quit all Office applications.
Open Finder and navigate to: ~/Library/Group Containers/UBF8T346G9.Office/
Delete the Identity folder.
Open Keychain Access, search for the following terms, and remove all related entries:
- Microsoft Office
- ADAL
- MSOID
Restart your Mac. Open any Office application and sign in again with your work account.
I hope these steps help resolve the issue. When you have a chance, please share an update on the outcome, as your feedback may be valuable to other community members experiencing a similar challenge.
