What I subscribed is Microsoft 365 Family, and have updated to the newest version.

My system is macOS Monterey 12.0.1
136d9b2b-064f-4ea6-bab3-f0ee4be2433b

The error page is as follows. You can see that it requires login again although I have login.

The problem is not because of individual add-ins, but all office add-ins fail to install.

    Hi @94808387

    Welcome to Q&A forum ~

    Could you please test Office online apps? (Please note, Office Online requires OneDrive to store files, but using OneDrive in some regions requires a VPN connection.)
    Such as Word online, you can go to Insert tab > Add-ins group, click Add-ins button, and then check this issue again.

    • I also suggest you sign out your accout from Office apps, make sure all Office apps are closed.

    • Then go to Finder > Go > Utilities > Keychain Access.
      In Keychain Access, select the "Passwords" category on the left, find the crendentials related to Office and remove it.
      Go back to Office apps, sign your account back to have a check.
