Hi Donia,
From your post, we understand AutoSave if off for the document stored in SharePoint online.
There are several reasons AutoSave could be disabled. Here are some common reasons for it to be disabled:
- File is in an older format like .xls, .ppt, or .doc.
- File is in a local OneDrive folder and OneDrive synchronization is paused.
- File is embedded inside another Office file.
- PPT presentation is in slide show mode.
If you are using Excel, and tried the above, you may have a file that contains features that are not supported by AutoSave.
- Shared Workbook feature is on.
- File is encrypted with password.
- Turn off the Refresh data when opening file setting on all tables and PivotTables in the file.
- Some add-ins are enabled that are causing AutoSave to be disabled.
Besides, please open the affected document from within Office app, instead of directly opening it from SharePoint or OneDrive sync client (File Explorer). To do this, follow the steps below:
- Open Word or Excel (app in which you are trying to open the file), click File>Open.
- Select your SharePoint, click the site name in which the file is stored under
Frequent or Following heading.

If the issue persists, please provide us with the following information:
- Please provide the screenshot of Microsoft 365
Product Information. To get this screenshot, open any Office app such as Excel or Word on your computer, click File>Account, capture the screenshot of all the information mentioned under Product Information.
- May I know the file format of the affected file? Is it .xlsx or .xls or docx etc?
- Is this happening to a specific file? To confirm this, try opening another file from your OneDrive for business.
- Please provide the screenshot of the document header that has the issue.
Let us know the status. Have a nice day and stay safe😊
Regards,
Neha
