Hi,
The error code 2148073494 is a common error that occurs when trying to sign in to Microsoft Office applications. It can be caused by outdated or corrupted login details saved within an app or within Windows. Here are some steps you can try to resolve the issue:
- Log out and log back in: Log out of the app and log back in to see if the issue is resolved.
- Clear cache: Clear the cache of both the browser and the app to ensure that there are no outdated login details saved.
- Use Microsoft Support and Recovery Assistant: Use the Microsoft Support and Recovery Assistant to repair and then also to uninstall and reinstall the applications.
- Reset OneDrive: If you are using OneDrive, reset it by disconnecting your work account from Windows Settings > Accounts > Access work or school > find your Microsoft 365 work account and click Disconnect. Then, open Credential Manager > go to Windows Credentials > Generic Credentials > remove OneDrive Business credentials which is like OneDrive cached Credentials Business, Uninstall OneDrive and Reinstall OneDrive to check the outcome .
If none of these steps work, you can try updating your Office to the latest version
Thank you,
Sai
