How to Stop Microsoft 365 Signing Out After Every Restart
Question details
The user needs to stop Microsoft 365 and OneDrive from repeatedly requesting sign-in after every Windows restart because cached credentials or the Microsoft 365 configuration are damaged.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- After a Windows restart, Office applications and OneDrive keep asking the user to sign in again, disrupting access to documents and cloud files.
- Observed behavior
- Microsoft 365 signs out automatically or prompts for credentials after every restart even though the user previously signed in.
Before changing credentials, make sure you know your Microsoft 365 account password and can approve any multi-factor authentication prompt. Close all Office applications and save your work so you can restart the computer safely.
Remove Corrupted Microsoft 365 Credentials from Windows Credential Manager
Use this first when OneDrive or Office keeps prompting for sign-in after each Windows restart and you suspect cached credentials are corrupted.
Windows stores Microsoft 365 and Office activation credentials in Credential Manager. If these entries are damaged or outdated, Office and OneDrive cannot retain your sign-in state after a restart.
Press the Windows key, type Credential Manager, and select the Credential Manager Control Panel item from the search results.
Click Windows Credentials, then locate entries that mention MicrosoftOffice, OneDrive, Outlook, or your Microsoft 365 account.
Select each relevant credential, click Remove, and confirm Yes to delete the cached sign-in data.
Restart the computer, open an Office application such as Word or Excel, sign in with your Microsoft 365 account, and check whether the sign-in persists after another restart.
