    If Microsoft 365 can open files but cannot write, edit, or save after an update, the supported fixes are:

    1. Update the operating system first, then update Office apps.
      • On macOS and iOS, unsupported OS or app versions can put Office into reduced functionality mode, where files can open and print but cannot be edited or saved.
      • Minimum supported versions listed are:
        • Mac: macOS 12 or later, Office version 16.83
        • iPhone/iPad: iOS 17.0 or later, app version 2.93
    2. If already updated but still cannot save, quit the app and sign in again.
      • 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.
    3. Install the latest Office updates.
      • On Mac: open any Office app, then select Help > Check for Updates.
      • For save failures tied to known issues, Microsoft’s documented resolution is to install the latest Office update.
    4. If files are stored in OneDrive, check OneDrive storage.
      • If OneDrive is full, documents stored there cannot be saved until storage usage is reduced.
      • Check space from the OneDrive icon in the notification area and choose Manage storage.
    5. If the problem is with OneDrive-synced files, restart or relink OneDrive.
      • Restart OneDrive and the affected Microsoft 365 app, then sign in again with the same account.
      • If needed, unlink and relink OneDrive.
      • Install available Windows updates if this is happening on Windows with OneDrive-synced files.
    6. If the file opens read-only, check activation.
      • An Unlicensed Product or activation problem can prevent editing and saving.
