Hello Kieran Ingham-Burroughes,
Thank you for using Microsoft products and posting them to the community.
Understand that you are having issues with auto saving word documents on your Mac. You can always correct me if my understanding is wrong.
Wanted to clarify with you that Office 2016 is no longer supported. But you can try the following suggestions to see if they work:
- would like to know if you have iCloud synchronization software installed on your Mac computer?
If iCloud is installed, since OneDrive and iCloud are both synchronization software, there may be a conflict and you can cancel the iCloud synchronization function.
2.You can try the following steps to restore OneDrive:
① Go to the OneDrive website Personal Cloud Storage – Microsoft OneDrive. (Make sure you sign in with the correct account.)
② If you are logged in using a personal account with a Microsoft 365 subscription, select Settings > Options at the top of the page, and then select Restore OneDrive from the left-hand navigation. Restore OneDrive” from the left-hand navigation.
③ On the Restore OneDrive page, select a date from the drop-down list, such as “Yesterday”, or select “Custom date and time”. If you restore files after automatic ransomware detection, the system populates a suggested restore date.
④ Use the Activity Chart and Activity Source to review the most recent activities that you want to undo.
⑤ Select the earliest activity you want to undo if you selected “Custom date and time”. When you select an activity, all other activities that occurred after that activity are automatically selected.
⑥ When you are ready to restore OneDrive, select “Restore”. This will undo all of the selected activities.
OneDrive Files () will revert to the state before the first activity selected.
It's important to note: When you restore, any files or folders created after the restore point date will be sent to the OneDrive Recycle Bin.
Refer to the link for detailed information: Restore your OneDrive - Microsoft Support.
Thank you for your understanding and patience. If you have any questions, feel free to reply.
