A family of Microsoft word processing software products for creating web, email, and print documents.
Hi, @Marys Access Clinic, PLLC
This message usually means Word and Excel on your Mac are holding on to old or mixed-up sign-in info. Because of that, they can't confirm your subscription even if it's still active.
Here are some suggestions you can try:
Quit all Office apps, then go to Finder > Applications > Utilities > Keychain Access. Search for "Office", "ADAL" and "AzureAD", and delete the entries that come up. Restart your Mac, open Word and sign in again. Office uses these saved logins to check your license, so clearing them makes it check again from scratch.
If that doesn't work, quit Office again. In Finder, click Go > Go to Folder, type ~/Library/Group Containers and press Enter. Move these three folders to the Trash: UBF8T346G9.ms, UBF8T346G9.Office and UBF8T346G9.OfficeOsfWebHost. Empty the Trash, then reopen Word and sign in.
Check where you got Office. If you downloaded Word and Excel from the Mac App Store, delete them and reinstall them from microsoft365.com. One-time purchase licenses don't work with the App Store versions. After that, go to Help > Check for Updates and install everything available.
Your work or school email might also be set up as a personal Microsoft account. If so, it's recommended to add a different email as an alias on the personal account and make it the primary one. That way, Office stops mixing up the two accounts.
Let me know how it goes!
