Cached Credentials expired

Question

I see multiple people have been having this issue! Was there any answer as to how to fix this? Powerpoint is saying my credentials have expired and it is not saving my file or allowing them to uploaded properly. I cannot continue to have this pop up every single time.

Hi @CC, 

Thank you for posting your question on the Microsoft Q&A forum. 

Regarding the error message “Cached credentials have expired,” I’d like to gather a bit more information to better understand your situation and assist you effectively: 

• Does this issue also occur with other Office applications such as Word or Excel? 
• Are other users in your organization experiencing the same problem? 

In the meantime, you can try the following steps:  

Note: Before performing the steps below, please make sure all your files are fully synced to OneDrive to avoid any potential data loss. 

Clear Office Credentials:    

• Remove the Work Account:   
• Go to Settings > Accounts > Work or School Account, select your account, and choose Disconnect. 

Clear Credentials:   

• Head to Control Panel > Credential Manager and remove any cached Microsoft 365 or Office credentials.   
• Try Re-adding the Account:   
• Once everything’s cleared, go back to Settings > Accounts and re-add your work account.   

Locate the Microsoft directory  

• Navigate to:   C:\Users<YourUserName>\AppData\Local\Microsoft  
• Delete the IdentityCache folder  
• Open the “OneAuth” folder. Inside, you’ll typically find subfolders like “blobs” and “accounts,” each containing information about your sign-in sessions.   
• Delete the “blobs” and “accounts” folders  
•  Restart an Office app and sign in again  

Repair Office   

• Right-click the Start button (lower-left corner) and select Installed apps on the pop-up menu.    
•  Select the Microsoft 365 or Office product you want to repair, click the ellipses, and select Modify.    
• If you see a notification that say " allow the change on your device" click yes. Then select online repair    

Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.      

I really appreciate your patience, and I’m here to help. Looking forward to your response.

Answer 2

PowerPoint credential and upload issues are typically caused by cached or corrupted sign-in data, especially when saving to OneDrive or SharePoint. Use these steps to clear cached credentials and then sign in again.

1. Clear OneDrive/Office cached credentials (Windows)
   1. Press Windows key + R.
   2. Paste and run:

            %localappdata%\Microsoft\OneDrive\settings
      

   3. In that folder, delete the file PreSignInSettingsConfig.json.
2. Remove stale credentials from Windows Credential Manager
   1. Open Control Panel → Credential Manager → Windows Credentials.
   2. Find and remove any entries related to Microsoft Office, Microsoft 365, OneDrive, or the affected work/school account.
   3. Close Credential Manager.
3. Restart apps and sign in again
   1. Exit PowerPoint and OneDrive completely (right‑click the OneDrive icon in the taskbar and close it).
   2. Start OneDrive again and sign in with the correct account.
   3. Open PowerPoint, sign in with the same account, and try saving/uploading the file again.
4. If the issue persists
   1. Unlink and re‑link OneDrive for the affected account (see Unlink and re‑link OneDrive in the referenced article).
   2. Make sure Windows is fully updated, then restart and test saving from PowerPoint to OneDrive/SharePoint again.

After these steps, PowerPoint should stop repeatedly prompting that credentials are expired and should save and upload files normally.
