How to Remove an Old University Account from Microsoft Apps on Mac
Question details
The user is unable to sign in to Microsoft applications on a Mac with a personal account because the system automatically defaults to an old university account.
- Product
- Microsoft Office
- Device & OS
- macOS
- Scenario
- Attempting to switch from an expired university Microsoft account to a personal Microsoft account on Mac applications.
- Observed behavior
- Microsoft apps persistently auto-fill and reject the personal account in favor of the old university account, even after clearing Keychain entries and reinstalling the software.
Ensure you have your correct personal Microsoft account email and password ready, and fully quit all running Microsoft applications on your Mac before starting.
Clear Browser Credentials and Reset Application Sign-in
Remove cached university credentials from your browser's password manager, which may be auto-filling the Microsoft login prompt.
Even when macOS Keychain entries are deleted, Microsoft applications often pull login tokens or auto-fill data directly from your default web browser (like Safari or Chrome). Clearing these specific browser credentials stops the apps from defaulting to the school account.
Open your default web browser (e.g., Safari or Google Chrome). Access the browser's password manager settings and search for 'Microsoft', 'Office', or your university portal. Delete any saved credentials associated with your old university account.
Open any installed Microsoft application on your Mac (such as Word or Excel). Click on the application name in the top menu bar, select 'Sign Out', and then completely quit the application.
Click the Apple logo in the top-left corner of your screen and select 'Restart'. This clears out temporary session states that might be holding onto the old login data.
Launch the Microsoft application again. Click 'Sign In' and carefully enter your personal Microsoft account credentials, ensuring you do not click any auto-fill prompts.
Contact the University Administrator or Microsoft Support
If local credential resets fail, your Mac may still be tied to the university's device management system.

Frequently Asked Questions
Why does uninstalling and reinstalling Microsoft Office on my Mac not fix the sign-in loop?
Uninstalling Microsoft Office by just dragging the apps to the Trash does not remove the hidden licensing and credential files stored in your Mac's Library and Keychain. When you reinstall, the new app finds these old hidden files and automatically logs you back into the university account.
Is there an official tool to remove old Microsoft licenses on Mac?
Yes. Microsoft provides an official 'License Removal Tool' for Mac. Downloading and running this tool will clear all Microsoft 365 and Office licenses from your device, which is highly effective for fixing account conflicts.
Can my Mac's password manager conflict with my personal Microsoft login?
Yes. If iCloud Keychain or your default browser's built-in password manager has your university email and password saved for Microsoft domains, it may force an auto-login or redirect you to the university's sign-in page, rejecting your personal account attempt.
