Solution 1Recommended

Verify Internet Connectivity and Test OneDrive Web Access

Determine if the issue is isolated to the desktop application or if it is an account-wide connectivity problem.

Often, sync and login errors are caused by temporary network disruptions or backend server issues rather than the app itself. Testing the web version helps isolate the problem.

Check your internet connection

Verify that your computer is connected to a stable Wi-Fi or Ethernet network by opening a web browser and navigating to any standard website.

Log into OneDrive via a web browser

Go to the official Microsoft OneDrive website and attempt to log in with your credentials. If the web version is accessible, the issue is isolated to your local Windows application.

Document the correlation ID

If the error persists or you need to escalate the issue, take a screenshot or write down the exact Error Code (2148073494), Correlation ID, and timestamp shown in the prompt for Microsoft Support.
