Problem with sign in on OneDrive

Try these steps in order:

1. Verify the account can sign in outside the OneDrive app.
   • For a personal account, sign in to your Microsoft account.
   • For a work or school account, sign in to Microsoft 365.
   • This confirms whether the issue is the account itself or only the OneDrive app.
2. Make sure the correct account type is being used.
   • OneDrive sign-in can fail if personal account credentials are used for a work or school account, or the reverse.
   • In the OneDrive app, select the OneDrive icon in the taskbar notification area.
   • Select Help & Settings > Settings > Account.
   • Confirm the expected account is shown. If not, sign in with the correct account.
3. If the OneDrive icon is gray or has a line through it, sign in again.
   • Select the grayed OneDrive icon.
   • At Set up OneDrive, enter the email address and password.
4. If OneDrive says it is not connected, restart OneDrive.
   • Open Start and search for OneDrive.
   • Launch it again and try signing in.
   • If OneDrive is missing, install the latest version from the download page.
5. If another or older account was previously added, unlink and relink OneDrive.
   • This is recommended when sign-in errors are caused by an old or incorrect account being attached.
6. Reinstall OneDrive if the issue continues.
   • Note: uninstalling and reinstalling OneDrive does not remove cloud data.
   • Open Add or remove programs.
   • Under Apps & features, select Microsoft OneDrive > Uninstall.
   • Download and install the latest OneDrive app.
   • Open it and complete sign-in again.
7. Check network blocking if sign-in still fails.
   • A firewall, VPN configuration, or internet provider can block OneDrive sign-in.
   • Test with a mobile hotspot if available.
   • If that works, check whether the current network, firewall, or provider is blocking Microsoft 365 or OneDrive access.
8. If signing in to a work or school OneDrive site shows tenant/account mismatch errors, use the work or school Entra ID instead of a personal Microsoft account.
9. If the issue is only with a work or school account and the correct account still cannot sign in, contact the organization’s IT admin or helpdesk.
10. If the issue is with a personal account and it still fails after the steps above, check the OneDrive service status or contact Microsoft Support.
