Clear Mac Keychain Credentials and Remove Office License Files
Removing corrupted credentials from Keychain Access and utilizing the official license removal tool usually resolves account recognition loops.
macOS stores your sign-in credentials in an app called Keychain Access. When these stored credentials become corrupted or out of sync with Microsoft's servers, Office fails to recognize your license. Clearing these old files forces the software to authenticate fresh.
Sign out of your account in any open Office applications, then fully quit all Office apps including Word, Excel, and PowerPoint.
Open Finder, navigate to Applications > Utilities, and double-click to launch the Keychain Access application.
In the Keychain Access search bar, type 'Microsoft Office'. Select and delete any associated credential files, passwords, or identities listed.
Download and run the official Microsoft Office License Removal Tool for Mac. Follow the on-screen prompts to clear all damaged license files.
Restart your Mac, open Microsoft Word, and sign in again using your officially licensed email address to activate the suite.

Perform a Clean Reinstallation of Office 2019 for Mac
If clearing the license files fails, a complete removal and fresh installation of Office can eliminate deep-seated configuration errors.
