Autosave function won't open in Word

Question

My autosave function stopped working in Word. It won't come on and I took it to BestBuy and their Geek Squad said it had to be a glitch in the software. I am using a MacBook Air M2 2022 version and updated Microsoft 365 in early February. It just stopped working last week and no one can get it to open. So frustrated that I can't speak to a person or chat with a person for support.

Answer 1

To summarize what the bot said, AutoSave only works with OneDrive or SharePoint. If you are saving files locally on your hard disk, it does nothing.

If, after trying the bot's advice, the problem is still there, try creating a new user account (System Settings>Users & Groups), signing in to that, then testing if the problem still exists. If it goes away, it's an issue with the user profile part of your Office installation.

Answer 2

If you haven't updated Office since early February that could be the problem... There have been 4 additional updates since 10 February. The present release on all currently supported editions of macOS is 16.107 which shipped on 10 March.

Exactly what does happen when you click the toggle switch? Are there any notifications or messages of any kind?

A long shot, but is your MS365 Subscription paid up?

On macOS, AutoSave in Word only works under specific conditions. Use the following checks and fixes in order:

1. Confirm where the file is saved

• AutoSave is enabled only when the document is stored in:
  • OneDrive / OneDrive for Business, or
  • SharePoint Online
• If the file is on the Mac’s local disk, a file server, or SharePoint on‑premises, AutoSave will be disabled.
• Save the document to OneDrive or SharePoint from within Word:
  1. In Word, select File > Save As.
  2. Choose a OneDrive or SharePoint location.
  3. Save the file and check the AutoSave toggle again.

2. Open the file from within Word (not Finder)

• On Mac, the file must be opened via Word’s File menu for AutoSave to activate.
  1. Open Word.
  2. Select File > Open.
  3. Choose the OneDrive or SharePoint location and open the document.
• If File > Open shows a special view, use the Online Locations button and then pick the OneDrive/SharePoint file from there.

3. Check common reasons AutoSave is disabled In Word for Mac, AutoSave can still be off for these reasons:

• The file is in an older format: .doc, .xls, .ppt. Save it as a modern format (e.g., .docx).
• The file is in a local OneDrive folder while OneDrive sync is paused.
• The file is embedded inside another Office file.
• For PowerPoint, the presentation is in slide show mode (not applicable to normal Word docs, but relevant if testing across apps).

4. Verify AutoSave settings in Office

• In Word, go to File > Options > Save (on Mac, use Word preferences for Save options) and ensure the AutoSave option is enabled for cloud files.

5. If using Excel and seeing similar behavior

• Some Excel features block AutoSave. To re‑enable it, do one or more of:
  • Turn off the legacy Shared Workbook feature.
  • Remove password encryption: Review > Protect Workbook, clear the password.
  • Remove restricted access: File > Restrict Permissions > No Restrictions.
  • If opening a SharePoint snapshot, open the actual workbook instead of the snapshot.

If after saving to OneDrive/SharePoint and opening via File > Open AutoSave is still off, the most likely causes are: the file is not in a supported format, OneDrive sync is paused, or the file is not truly being opened from an online location.
