Fix Word for Mac Redirecting to a University Sign-In Portal
Question details
The user needs to prevent Microsoft Word for Mac from forcing a sign-in through a university portal so they can log in with a personal Microsoft account.
- Product
- Microsoft Word
- Device & OS
- Mac
- Scenario
- Attempting to sign into Word for Mac with a personal account after previous university credentials have expired.
- Observed behavior
- Word redirects sign-in attempts to a university SSO portal and rejects university credentials, trapping the user in a login loop.
Before clearing your Microsoft Office cache and container files, make sure to back up any unsaved documents and your Outlook data to prevent accidental data loss.
Clear Office Credentials and Reset Container Files
Removing cached Microsoft credentials from Keychain Access and deleting Office group container files will force Word to prompt for a fresh sign-in, allowing you to use your personal account.
Microsoft Office for Mac frequently caches login tokens to keep you signed in. When switching from a university account to a personal one, these cached tokens can force the application to repeatedly load the university's Single Sign-On (SSO) page. Clearing these files manually resolves the conflict.
Open Microsoft Word, sign out of your current account, and then completely quit Word and all other Microsoft Office applications running on your Mac.
Open the Keychain Access application on your Mac. Use the search bar to find and delete any passwords or credentials related to 'MicrosoftOffice'.
Open Finder, press Command+Shift+G to open the 'Go to Folder' window, and type ~/Library/Group Containers. Locate and move the folders named UBF8T346G9.ms, UBF8T346G9.Office, and UBF8T346G9.OfficeOsfWebHost to the Trash.
Restart your Mac. Open Microsoft Word, and you will now be able to proceed with a fresh sign-in using your personal Microsoft account.
Avoid Microsoft Account Login Loops with WPS Office
If Microsoft Word's constant sign-in prompts, credential issues, and SSO portal redirects disrupt your workflow, consider switching to WPS Office. It provides a lightweight, hassle-free environment to read, edit, and create Word documents without complex login barriers.
- 1. Download WPS Office: Visit the official WPS website and download the free WPS Office installer for Mac.
- 2. Install the Application: Open the downloaded package and follow the on-screen instructions to install WPS Office on your Mac.
- 3. Open Your Documents: Launch WPS Office and directly open your existing .docx files to continue working seamlessly.
Frequently Asked Questions
Why does Word for Mac keep asking for my old university login?
Word often caches old login tokens in the Mac Keychain and Group Container folders. If these aren't manually cleared, Word defaults to the old organization's Single Sign-On (SSO) page instead of the standard Microsoft login page.
Will deleting the UBF8T346G9 folders delete my Word documents?
No, deleting these Group Container folders resets Office preferences and cached login states, but it does not delete your locally saved Word documents. However, it may remove local Outlook data, so backing up Outlook is highly recommended.
How do I switch my Office license from a university account to a personal one?
First, sign out of the university account in any Office app. Then, clear your Mac's Keychain of Office credentials and run the official Microsoft License Removal Tool before signing back in with your personal account.
What if Word still redirects to the university portal after clearing the cache?
If the issue persists, you may need to completely uninstall Microsoft Office for Mac, remove the cached license files using the Microsoft License Removal Tool, and reinstall the suite directly from your personal Microsoft account dashboard.
