Outlook Keeps Asking for Your Password? Break the Loop

Daily password prompts that never stick — credential cache, MFA app vs SMS, and the profile rebuild that ends it.

  1. 1. Clear stale credentials

    Control Panel → Credential Manager → Windows Credentials → remove every Outlook/Office/Microsoft entry. A changed password plus a cached old token is the classic loop — Outlook keeps offering the dead token.

  2. 2. Switch MFA to the Authenticator app

    SMS-code MFA plus Outlook's modern auth argue constantly. Approve sign-ins from Microsoft Authenticator instead — then sign into Outlook fresh once. The loop usually ends here.

  3. 3. Rebuild the Outlook profile if it persists

    Control Panel → Mail → Show Profiles → Add a new profile, set it default. A corrupt profile keeps requesting auth no matter what you type. Your mail re-downloads from the server — nothing is lost.

Outlook Keeps Asking for Your Password? Break the Loop — When to Call a Pro

  • The whole office loops at once — likely Conditional Access, expired cert, or license issue.
  • It's tied to a migration or tenant change needing admin-side fixes.
  • You want MFA rolled out properly so the loop never comes back.

Guide FAQ

Every cached copy of the old password — Outlook, phone mail apps, Teams — fights the new one. Update all devices the same day and clear Credential Manager.
On your own encrypted device, yes. On shared or public machines, never — use webmail instead.
