- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Switching from a university or work account to a newly purchased personal Microsoft 365 subscription on the same device.
- Observed behavior
- Office applications fail to activate, likely because the software is still attempting to authenticate using the old university account credentials.
Before troubleshooting, ensure your device is connected to the internet and you have the correct login credentials for your newly purchased Microsoft 365 Personal account ready.
Verify Account Association and Subscription Status
Check if your Office applications are still linked to your old university account and verify that your new subscription is active online.
When switching subscriptions, Office applications often retain the credentials or license tokens from the previous account. This causes activation conflicts, as the software attempts to verify an expired university license instead of your new personal one.
Open any Office application, such as Word or Excel. Click on 'File' in the top-left corner and select 'Account' from the menu on the left side.
Under the 'Product Information' section, check which email address is currently signed in and carefully read any activation error messages displayed.
If your university account is still listed, click 'Sign out'. Restart the Office application and sign back in using your new personal Microsoft account.
Open a web browser and sign in to account.microsoft.com with your new personal Microsoft account. Navigate to the 'Services & subscriptions' section to confirm your Microsoft 365 Personal subscription is active.

Frequently Asked Questions
Why does my Office app still show my old university account after my subscription ended?
Office caches your previous license and login credentials locally on your device. Even if the university subscription has expired, the device holds the old license token until you manually sign out and switch accounts under File > Account.
Do I need to uninstall and reinstall Office when switching from a university to a personal account?
In most cases, you do not need to reinstall Office. Signing out of the old account and signing in with the new personal account under File > Account is usually sufficient to update the license, provided the new subscription is active.
How do I remove the old university account credentials from my Windows PC completely?
Go to Windows Settings > Accounts > Access work or school. Locate your university account in the list, click on it, and select 'Disconnect' to remove its credentials and prevent Office from trying to use it for activation.
