How to Stop PowerPoint from Asking to Save Unchanged SharePoint Files
Question details
The user is repeatedly prompted to save PowerPoint files upon closing them, even when no edits have been made.
- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Opening and viewing a PowerPoint presentation hosted on SharePoint without checking it out or making any modifications.
- Observed behavior
- PowerPoint incorrectly detects changes and asks if the user wants to save the SharePoint file upon closing, likely due to a conflict within the Office Document Cache.
Ensure your presentation does not contain macros, volatile Excel links, or auto-updating date/time fields, as these elements refresh upon opening and will legitimately trigger a save prompt.
Clear and Auto-Delete Office Document Cache Files
Clearing the Office Document Cache and setting it to delete automatically prevents PowerPoint from holding onto temporary files that incorrectly flag unedited documents as modified.
The Microsoft Office Document Cache is designed to help files open quickly from SharePoint. However, when cached files become corrupted or out of sync, PowerPoint may mistakenly believe a file has unsaved changes.
Launch PowerPoint, click on the 'File' tab in the top-left corner, and select 'Options' at the bottom of the left-hand menu. Then, click on 'Save' in the Options dialog box.
Scroll down to locate the 'Cache Settings' section. Check the box labeled 'Delete files from the Office Document Cache when they are closed'.
Click the 'Delete cached files' button and confirm the action when prompted.
Close PowerPoint completely and reopen it. Open your SharePoint file again to verify that the phantom save prompt no longer appears when closing.
Test Alternative Files and Update Office
If clearing the cache does not resolve the issue, determine if the problem is specific to a single corrupted file or an outdated version of Office.

Frequently Asked Questions
Why does PowerPoint think I made changes to a read-only SharePoint file?
This generally happens because corrupted Office Document Cache files create a sync conflict, or because the presentation contains elements that update automatically upon opening, such as the 'Today's Date' field or linked Excel charts.
Will deleting cached files remove my actual SharePoint documents?
No. Deleting the Office Document Cache only removes temporary local background files used by Office to speed up opening documents. Your actual documents on SharePoint remain completely safe and untouched.
How do I stop all automatic date updates in my PowerPoint slides?
Go to the 'Insert' tab, click 'Date & Time', and ensure the 'Update automatically' checkbox is unticked. Click 'Apply to All' to ensure fixed dates are used across your entire presentation.
Can I completely disable the Office Document Cache to prevent this permanently?
You cannot completely disable the caching feature in Microsoft Office, but by checking 'Delete files from the Office Document Cache when they are closed' in your Save options, you force Office to clear the cache automatically, which effectively mimics disabling it and minimizes issues.
