Microsoft 365 issues on macbook

On Mac, this usually means the Office apps are not recognizing the correct license, the apps are outdated, or the apps have gone into reduced functionality mode.

Try these steps in order:

1. Confirm the subscription is active
   • For Microsoft 365 Personal or Family, sign in to Services & subscriptions and verify the subscription is active.
   • If using a work or school account, sign in to My Account and check the Subscriptions tile.
2. Check which product is installed on the Mac
   • Open Word.
   • Select Word > About Word.
   • If it shows Microsoft 365, the subscription version is installed.
   • If it shows Office 2021 or Office 2019, that is a perpetual-license version.
3. Sign out and sign back in
   • If editing and saving are blocked after updating, quit the app completely with Command + Q.
   • Reopen the app.
   • Go to the app’s Account settings, sign out, then sign in again with the Microsoft account tied to the subscription.
4. Update macOS first, then update Office
   • Starting July 13, 2026, unsupported macOS or Office versions can cause Office apps to open and print files but not edit, save, or create new files.
   • Minimum supported versions to update successfully are:
     • Mac: macOS 12 (Monterey) or later
     • Office app version: 16.83 or later
5. If the apps still will not activate or save/edit, reinstall Office
   • A full uninstall and reinstall can fix license recognition problems on Mac.
   • Reinstall from the Microsoft account used for the subscription so the correct license is applied.
6. If AutoSave is the specific issue
   • AutoSave only works when the file is saved to OneDrive, OneDrive for Business, or SharePoint Online.
   • It is disabled for files in a local Mac folder, on a file server, or on SharePoint Server on-premises.
   • It can also be disabled for older file formats such as .doc, .xls, or .ppt.

If the Mac is on an older OS or the Office apps are below version 16.83, update those first. If the subscription is active but Word still opens documents in view-only mode, sign out/in and then reinstall Office if needed.
