Fix OneDrive Changing File Modified Dates When Opening Documents
Question details
The user wants to prevent file modified timestamps from updating automatically when a document is opened but not edited.

- Product
- Microsoft OneDrive and Word
- Device & OS
- not provided
- Scenario
- Opening a synced document stored in Microsoft OneDrive to view its contents without making any changes.
- Observed behavior
- The file's modified date updates immediately upon opening, likely caused by AutoSave or a background synchronization process writing to the file.
Ensure your OneDrive client is actively running and fully synced to rule out any delayed synchronization issues affecting file metadata.
Disable AutoSave in Microsoft Word
Turning off AutoSave prevents Word from automatically writing to the file upon opening, which stops the modified date from changing unnecessarily.
When AutoSave is enabled for Microsoft 365 files, opening a document triggers an initial save operation to prepare for real-time co-authoring. This background action alters the file's modified timestamp even if you do not type anything.
Launch Microsoft Word, click on the "File" tab in the top-left corner, and select "Options" at the bottom of the menu.
In the Word Options dialog box, click on "Save" in the left-hand navigation pane.
Uncheck the box labeled "AutoSave OneDrive and SharePoint Online files by default on Word". Click "OK" to apply your changes.
Create a copy of a file in your OneDrive folder and open it to verify that the modified date no longer changes automatically.

Check OneDrive Sync Status and Report the Issue
If disabling AutoSave does not resolve the timestamp changes, there may be a defect or delay with your OneDrive synchronization service.

Frequently Asked Questions
Why does simply opening a file change its modified date in OneDrive?
When AutoSave is enabled in Microsoft 365, opening a cloud-synced file triggers a background save operation to establish a connection for real-time co-authoring. This initial background write operation updates the modified timestamp even if you haven't typed anything.
Will disabling AutoSave prevent real-time collaboration?
Yes. AutoSave is required for real-time co-authoring in Microsoft Word, Excel, and PowerPoint. If you disable it to prevent file timestamps from changing upon opening, you will need to save manually, and others will not see your edits in real time.
Why is there a delay in modified dates syncing across multiple devices?
Sync delays can occur due to network connectivity issues, background service throttling, or pending application updates. Changes made on one device may sometimes take 20 to 30 minutes to appear on another device unless manually refreshed or forced to sync.
How can I view the actual last edited time of a document?
You can check the document's version history in OneDrive or right-click the file in Windows File Explorer, select 'Properties', and view the 'Details' tab to see both creation and modification metadata.
