UPLOAD BLOCKED

Question

Problem Statement:

UPLOAD BLOCKED - We ran into a problem with this file and can't save any new changes. Please save a copy to avoid losing your work.

Since:

• ✅ PowerPoint in the browser shows the latest updates from other users.
• ❌ PowerPoint desktop app does not show the latest updates.
• ❌ Desktop app shows UPLOAD BLOCKED.

Answer 1

This usually occurs when the desktop Microsoft 365 app is signed in with an account that does not have permission to upload to the OneDrive location for the file. That also explains why the browser version can show the latest updates while the desktop app cannot save them.

Try these fixes in order:

1. Verify the same account is used in OneDrive and PowerPoint desktop
   1. Select the OneDrive icon in the Windows taskbar notification area.
   2. Go to Help & Settings > Settings.
   3. On the Account tab, note the signed-in account.
   4. In PowerPoint desktop, go to File > Account.
   5. Under Connected Services, remove all accounts except the same account shown in OneDrive.
   6. In the OneDrive icon menu, select Help & Settings > Pause syncing and choose 2 hours, 8 hours, or 24 hours.
   7. Select Help & Settings > Quit OneDrive.
   8. Close PowerPoint and all other Microsoft 365 apps.
   9. Restart OneDrive and PowerPoint, then sign in again with the same account.
   10. Open the file and try saving again.
2. Clear stored OneDrive and Office credentials
   1. In PowerPoint, go to File > Account.
   2. Under User Information, sign out of all accounts.
   3. Close all Microsoft 365 apps.
   4. Open Start, type credentials, and open Credential Manager.
   5. Select Windows Credentials.
   6. Under Generic Credentials, remove entries related to OneDrive, MicrosoftOffice16, and MicrosoftOffice15.
   7. Restart OneDrive and PowerPoint.
   8. Sign in again using the same account in both.
   9. Try saving the file again.
3. If the issue continues, unlink and relink OneDrive This can fix OneDrive configuration issues. Use the steps in Unlink and re-link OneDrive, then test saving again.
4. Install available Windows updates After installing updates, restart PowerPoint and test the save again.

If work is currently unsaved, use Save a Copy first to avoid losing changes.
