Office Apps keep turning my files into .temp files

Use Microsoft’s official support page, select Microsoft technical support → Get help, describe the issue, and choose Contact Support or Chat when offered to reach the appropriate Microsoft 365/OneDrive technician.^1^

Contact Microsoft technical support

1. Open Contact Microsoft customer support.
2. Sign in with the personal Microsoft account associated with your Microsoft 365 subscription and OneDrive.
3. Under Microsoft technical support, select Get help.
4. Enter a precise description such as:

   Word, Excel, and PowerPoint files stored in OneDrive are being replaced by .temp files. The original filenames and contents disappear from the Windows drive. This affects multiple Office applications and previous community troubleshooting has not resolved it.

5. Continue through the prompts and select Contact Support, then choose Chat or another available technician-assisted option. Available contact methods depend on the product, subscription, region, and issue.^1^

If that page only displays automated suggestions, open the Windows Get Help app, enter the same description, and continue until Contact Support appears. Do not post filenames containing personal information, account details, or passwords in a public forum.

Protect and recover the affected files first

Until support investigates, avoid repeatedly opening or saving affected files. If possible, copy unaffected files to a folder outside OneDrive or to another storage device.

Check the cloud copies before changing the OneDrive installation:

1. Sign in to the OneDrive website.
2. Open Recycle bin.
3. Select missing original files and choose Restore. For personal OneDrive accounts, deleted items can normally be restored within 30 days unless they have been permanently deleted.^2^
4. For files that still exist but have lost content, use Version History and restore or download an earlier version. Microsoft documents Version History as the recovery option for earlier versions of Office files stored in OneDrive.^3^

If many files were changed, overwritten, or deleted and you have a Microsoft 365 subscription, restore the entire OneDrive to a point before the incident:

1. On the OneDrive website, select Settings → Options → Restore your OneDrive.
2. Choose Custom date and time immediately before the unwanted changes.
3. Review the activity feed carefully.
4. Select Restore.

This can undo file actions from the preceding 30 days. It is a broad rollback: files created after the selected restoration point are moved to the OneDrive Recycle Bin, so review the listed activities before proceeding.^4^

Information to give the technician

Prepare the following so support can distinguish an Office save problem from a OneDrive synchronization or Windows file-system issue:

• Whether affected files are inside the OneDrive folder.
• Whether the original files and content remain visible on the OneDrive website.
• The approximate time of the latest occurrence.
• Screenshots showing the original and .temp filenames, with personal details hidden.
• Whether the problem affects newly created files, existing files, or both.
• Your Windows version and the Office version shown under Word → File → Account → About Word.
• Whether files saved temporarily to This PC outside OneDrive show the same behavior.

The symptom alone does not establish why the files are being replaced, so recovery and technician diagnosis should precede further resets or repairs.
