Fix OneDrive Work Account Disconnecting After Every Restart (Error 1200)
Question details
The user needs to troubleshoot a persistent issue where their OneDrive work account automatically signs out or disconnects every time the computer is restarted, displaying error codes such as 1200, Error Tag 657rx, or 2150121473.
- Product
- OneDrive
- Device & OS
- Windows
- Scenario
- Rebooting the computer and expecting the OneDrive work account to sign in and sync automatically.
- Observed behavior
- The OneDrive application fails to authenticate automatically upon Windows startup, drops the work account connection, and returns Error 1200 or 2150121473.
Ensure you are logged into Windows with an Administrator account, as you will need administrative privileges to access Settings and repair the Microsoft Office installation.
Repair Microsoft Office via Windows Apps and Features
Use the built-in Windows repair utility to fix corrupted Microsoft Office authentication modules that cause OneDrive to drop work account credentials.
Microsoft 365 and OneDrive installed under a Windows administrator account are designed to sign in automatically when Windows starts. When core Office files or credential managers become corrupted, this automated sign-in fails, resulting in Error 1200.
Running a Quick Repair resets these authentication pathways without deleting your documents or requiring a full reinstallation.
Right-click the Windows Start menu and select 'Apps and Features' (or 'Installed apps' in Windows 11).
Scroll through your list of installed programs or use the search bar to find 'Microsoft Office' or 'Microsoft 365'.
Click on the application (or click the three dots next to it) and select 'Modify'. If prompted by User Account Control (UAC), click 'Yes' to allow changes.
In the repair dialog box, select 'Quick Repair' and click the 'Repair' button. Wait for the process to complete.
Once the repair is finished, restart your computer. Open OneDrive to verify if the work account connects automatically without throwing Error 1200.

Frequently Asked Questions
What does OneDrive Error Code 1200 mean?
Error 1200 typically points to an issue with Microsoft's authentication cache or corrupted credential folders. It prevents OneDrive or Outlook from properly verifying your login credentials when the system starts.
Will repairing Microsoft Office delete my synced files?
No. Running a Modify or Repair task from Windows Settings only affects the program files and registry keys of the Microsoft Office suite. Your personal documents, cloud files, and data remain completely safe.
Why does Error 2150121473 only happen on my work account?
Work accounts often utilize different authentication protocols (such as Azure Active Directory) and have stricter security policies than personal Microsoft accounts. This complexity makes them more prone to token expirations and credential caching glitches upon a system reboot.
