Question details

Users experience an issue where files opened from OneDrive download and open as local copies on Mac, causing the AutoSave feature to become unavailable.

Product: Microsoft OneDrive and Microsoft Office
Device & OS: macOS
Scenario: Opening cloud files stored in OneDrive via Microsoft Office applications on a Mac.
Observed behavior: Files open as local copies rather than cloud-synced documents, disabling the AutoSave feature. Reinstalling apps and restarting the Mac do not resolve the problem.

Before you start

Ensure you have your Mac administrator password handy, as you will need it to create a new user profile for testing compatibility issues.

Solution 1Recommended

Test with a New Local Administrator Account

Create a fresh macOS user profile to determine if the AutoSave failure is restricted to your current user environment or preferences.

Since this issue often stems from compatibility conflicts between macOS, OneDrive, and Microsoft Office, testing on a clean user profile helps isolate corrupted local settings.

Open Users & Groups

Click the Apple menu in the top-left corner of your screen, select 'System Settings' (or 'System Preferences'), and navigate to 'Users & Groups'.

Add a New Administrator Account

Click the 'Add Account' button. Authenticate with your current password, change the New Account type to 'Administrator', fill in the account details, and click 'Create User'.

Log In to the New Profile

Log out of your current Mac account and log in using the newly created administrator account credentials.

Test OneDrive and AutoSave

Launch OneDrive, sign in to your Microsoft account, and open a synced file in Word or Excel to see if the AutoSave toggle is now active and functioning.

Solution 2

Monitor for Official Microsoft and Apple Updates

Wait for and install the latest software patches, as Microsoft is actively investigating this compatibility issue on Mac.

Frequently Asked Questions

Why does AutoSave turn off when opening a OneDrive file on Mac?

This usually happens if the Office application fails to establish a direct connection with the cloud servers due to syncing conflicts. To prevent data loss, the app forces the file to download and open as a local copy, which inherently disables cloud-based AutoSave.

Does reinstalling OneDrive and Microsoft Office fix the AutoSave bug?

Typically, reinstalling and restarting do not resolve this specific compatibility issue. It is heavily tied to macOS and OneDrive system interactions, which is why testing on a new Mac user profile or waiting for an official software patch is recommended instead.

How do I force OneDrive to sync online rather than locally?

Ensure the 'Files On-Demand' feature is enabled in your OneDrive preferences. Also, make sure you are opening the file directly from the integrated OneDrive folder in Finder while logged into the associated Microsoft account in your Office applications.
