Remove and Replace Office License Files
Clearing corrupted license files often resolves persistent sign-in prompts on Mac, especially for Office version 16.54.
This method clears the activation data that may have become corrupted, allowing Office to properly save your sign-in credentials in the Mac Keychain.
Open Word, click 'Word' in the top menu bar, and select 'About Word'. Check if you are running version 16.54 or a similar build.
Go to the official Microsoft support site and download the Office License Removal Tool for Mac.

Frequently Asked Questions
Why does Microsoft Office keep asking me to sign in on my Mac?
This usually happens when the Mac Keychain fails to store your Office credentials correctly, or when the Office license files on your system become corrupted or outdated.
Will using the license removal tool delete my Word documents?
No. The license removal tool only clears the activation and credential data for Microsoft Office. Your personal files, documents, and presentations will remain completely safe and untouched.
Does this sign-out issue happen with Mac App Store versions of Office?
Yes, it frequently affects App Store installations. If the standard license removal tool doesn't work, you may need to perform a complete clean uninstall, clear the Mac Library container files, and reinstall the apps.
