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.

1
Quit all Office applications

Sign out of your account in any open Office applications, then fully quit all Office apps including Word, Excel, and PowerPoint.

2
Access Mac Keychain

Open Finder, navigate to Applications > Utilities, and double-click to launch the Keychain Access application.

3
Delete Microsoft Office identities

In the Keychain Access search bar, type 'Microsoft Office'. Select and delete any associated credential files, passwords, or identities listed.

4
Run the License Removal Tool

Download and run the official Microsoft Office License Removal Tool for Mac. Follow the on-screen prompts to clear all damaged license files.

5
Restart and sign in

Restart your Mac, open Microsoft Word, and sign in again using your officially licensed email address to activate the suite.

Frequently Asked Questions

Why does my Mac keep asking me to sign into Office 2019?

This usually happens when your Mac's Keychain credentials become corrupted, duplicated, or out of sync with your Microsoft account. Clearing the Office-related entries in Keychain Access typically resolves the continuous authentication prompts.

Will removing the Office license files delete my personal documents?

No, using the Microsoft Office License Removal Tool only deletes the system files associated with your product activation. Your personal documents, spreadsheets, and presentations will remain completely safe and unaffected on your Mac's hard drive.

How do I know which email account is linked to my Office 2019 license?

You can verify your licensed account by logging into the Microsoft account portal (account.microsoft.com) via a web browser. Navigate to the 'Services & subscriptions' section to see which email address holds your Office 2019 purchase.

What should I do if the Microsoft License Removal Tool doesn't fix the issue?

If the removal tool doesn't work, you will need to perform a clean uninstallation. This involves moving the Office apps to the Trash and manually removing hidden Microsoft folders from your Mac's Library (~/Library) folder before reinstalling the software.
