Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Marian Roja
Based on my research, the message you’re seeing usually indicates a change in licensing or in how your account is recognized by the Office apps.
Even if it was working earlier today, education tenants can apply updates or license changes that take effect immediately.
First, please check with your school or IT administrator to confirm your current license. You’ll want to verify whether your account still has a license that includes desktop Office apps (such as Microsoft 365 A3 or A5). If your account has been switched to an A1 (web-only) license, desktop editing on Mac is not supported and the apps will show view-only mode.
To try refreshing your Office activation:
- Open Word (or any Office app) > Go to Word > Settings > Account
- Sign out of your account > Close all Office applications completely
- Reopen Word and sign back in
If that doesn’t resolve it, you can clear cached credentials:
- Open Keychain Access on your Mac (Click the Finder icon > click Applications >Scroll down to find the Utilities folder > Keychain access) Search for entries related to: Microsoft Office, ADAL, AzureAD,...
- Delete those entries
- Restart your Mac and sign back into Office
You can also verify your current activation status in Word under “About Word” or the Account section to ensure it shows a valid licensed product rather than view-only.
If the issue appeared suddenly without any changes on your side, it is very likely due to a backend license or policy update by your school. In that case, your IT administrator will need to either reassign a license that includes desktop apps or confirm whether desktop editing is still supported for your account.
As a temporary workaround, you can continue editing documents using Office on the web through your browser.
I hope this information helps.
