Just purchased MS Office 2024 and can't save or save as any documents

I have a MacBook M1. I've made sure that the apps have access to all folders. I've re-installed twice. I have plenty of storage [Apple's equivalents to the MS apps all work fine]. I'm running Tahoe as no other upgrade options are listed. VERY Frustrated. VERY.

    On macOS, this usually points to Office running in reduced functionality mode or a license/update issue rather than disk space, especially since reinstalling and folder access checks were already done.

    Try this in order:

    1. Update Office fully
      • Close all Office apps.
      • Open Finder > Applications > Microsoft AutoUpdate.
      • Install all available updates.
      • Office on macOS should be on macOS 12 or higher for current licensing fixes.
      • After updates finish, reopen Word or Excel and test Save and Save As.
    2. Check whether Office is in reduced functionality mode
      • A recent known issue notes that Office apps on macOS can open and print files but cannot edit, save, or create new files.
      • If that matches the behavior exactly, updating Office is the required fix path.
    3. Refresh the license inside an Office app
      • Open Word.
      • In the macOS menu bar, select Word > About Word > More Info… > Refresh License.
      • Then close all Office apps completely and reopen them.
    4. If Office 2024 was installed over an older Office version, remove older license files
      • On Mac, older Office licenses can remain even after uninstalling the older version and can interfere with the new install.
      • This is especially relevant if there were previous Microsoft 365 or Office installs on the Mac.
    5. Reinstall from the Microsoft account install source if needed
      • If the issue continues after updating and refreshing the license, reinstall Office from the Microsoft account install source, then update again through Microsoft AutoUpdate.
    6. If a save attempt shows a disk-related error instead of greyed-out Save commands
      • Install the latest Office update from Help > Check for Updates in any Office app.
      • This is the documented first resolution for serious disk error/save failures on Office for Mac.

    A useful distinction:

    • If Save and Save As are greyed out, that aligns more with licensing/reduced functionality mode.
    • If Save is available but fails with a message like serious disk error, that aligns more with the Office for Mac save-process issue.

    MS Auto Update is not even listed under apps. Screenshot 2026-09-18 at 5.42.31 PM

    Both Save and Save as are grayed out. How do I fix the reduced functionality issue? And why would that be enabled?
