How to Stop OneDrive from Changing a File's Modified Date When Opened
Question details
Users need to stop files located in a local OneDrive folder from receiving a new modified date or generating a new version history entry when opened without any actual changes.

- Product
- OneDrive and Microsoft Office
- Device & OS
- not provided
- Scenario
- Opening, viewing, and closing Office files stored in a local OneDrive folder without making any manual edits.
- Observed behavior
- The file's modified date updates and a new version is recorded immediately upon opening, often caused by Microsoft Office's real-time AutoSave triggers.
Before altering your save settings, ensure you have manually saved any recent work, as the primary fix involves disabling the AutoSave feature, which changes how your documents are backed up to the cloud.
Disable AutoSave by Default in Office Applications
Turning off the AutoSave feature prevents Microsoft Office from actively communicating with OneDrive upon opening a file, thereby preserving the original modified date.
When AutoSave is enabled for Microsoft 365, the Office application immediately establishes a sync connection with OneDrive to enable real-time co-authoring. This connection registers as an update to the file, altering its metadata even if you only read the document. Disabling this feature resolves the issue, but requires you to rely on manual saving.
Launch the affected application, such as Excel or Word. Click on 'File' in the top left corner, then select 'Options' located at the bottom of the menu.
In the Options dialog box that appears, click on the 'Save' tab in the left-hand navigation pane.
Look for the option labeled 'AutoSave OneDrive and SharePoint Online files by default on Word/Excel' (or similar phrasing) and uncheck it. Ensure that 'Save AutoRecover information every X minutes' remains checked so you still have local emergency backups.
Click 'OK' to apply the new settings. Close and restart the Office application to ensure it stops triggering modified date changes when files are opened.

Frequently Asked Questions
Why does OneDrive change the modified date when I don't make edits?
This happens due to the AutoSave feature in Microsoft Office. When you open a file stored in OneDrive, AutoSave actively communicates with the cloud to prepare for real-time collaboration, which effectively updates the file's metadata and last modified time.
Will disabling AutoSave also turn off my AutoRecover backups?
No. AutoSave (which saves directly to the cloud in real-time) and AutoRecover (which saves a local backup copy every few minutes) are distinct features. You can safely disable AutoSave to fix the date issue while keeping AutoRecover active for emergencies.
Does this modified date issue happen with other cloud storage services?
Generally, no. This specific behavior is a result of the tight integration between Microsoft Office applications and OneDrive or SharePoint. Third-party services like Dropbox or Google Drive typically only update the modified date when actual file changes are written to the disk.
