Locked out of Microsoft 365? Here’s how to get back in.

Last updated

Being locked out of your Microsoft 365 account usually means too many failed password tries: Microsoft blocks sign-in to protect the account, even if your next guess would be right. Waiting rarely helps; a reset clears it. Work through these in order.

01 · Quick checks first.

  1. Stop guessing. By default the account locks after 10 failed attempts: one minute at first, then longer each time it happens again. More wrong guesses only extend it. A reset (step 02) clears it instantly.
  2. Read the message. “Your account is temporarily locked to prevent unauthorized use” is a genuine lockout, which is what this article covers. “Your account or password is incorrect” just means a wrong password, so slow down before you are locked out.
  3. Two accounts on one email? If your address is attached to both a work account and a personal Microsoft account, the “Work or school” vs “Personal” picker sends you to two different sign-ins. Choose Work or school account for anything your firm runs.
  4. Something else may be signing in as you. A phone’s mail app or a second PC retrying an old saved password trips the lockout again and again. If it keeps coming back, that’s almost always why (more in the FAQ).

02 · Reset it yourself instead of waiting.

Microsoft’s self-service reset clears the lockout on the spot:

  1. Go to aka.ms/sspr in any browser (a private or incognito window avoids cached sign-ins).
  2. Enter your work email and the characters shown, then choose I forgot my password. This matters: the “forgot” route resets the lockout timer to zero, while “I know my password” leaves it running.
  3. Verify it’s you (a code to your phone or authenticator app), set a new password, and sign in.

If the page says your organisation hasn’t enabled self-service reset, or you never registered a phone number for it, you can’t use this route. Go to step 03.

03 · Ask your admin for a reset.

Whoever runs Microsoft 365 at your firm (a manager, the owner, or your IT provider) can reset your password in about a minute: in the admin center, Users → Active users, select your name, Reset password. That unlocks the account immediately. They’ll give you a temporary password to change at next sign-in.

One caveat: if you’re stuck at the verification-code step rather than the password step, that’s a multi-factor authentication problem, not a lockout. Your admin needs to sort your sign-in methods before a password reset will help.

If you're the only admin and there is no IT person

Call Microsoft for Business in Australia on 13 20 58, choose option 2, then technical support. This is Microsoft's number, not KoalaFix support. Check Microsoft's current contact options.

Explain that you are the only Microsoft 365 administrator and cannot sign in. Have your company name, tenant domain, affected admin address, exact error and a reachable alternative email ready. Ask about administrator account recovery and ownership verification. Never share your password or MFA codes with an unsolicited caller.

04 · Or let KoalaFix do it.

That’s the whole checklist a good IT person would run, and unlocking accounts is what KoalaFix does. Whoever runs your Microsoft 365 tells it someone is locked out, and it checks the account and resets the password in about a minute. No admin center, no ticket.

05 · FAQ.

How long does a Microsoft 365 account lockout last?

One minute the first time, by default. Repeat lockouts last longer, and Microsoft deliberately doesn’t publish how much longer. You don’t have to wait, though: the “I forgot my password” reset at aka.ms/sspr clears it immediately.

Why does my Microsoft 365 account keep locking itself?

Something is still trying an old password on your behalf, usually a phone’s mail app, a second computer, or an app that saved your credentials before a password change. Each silent retry counts as a failed sign-in and re-locks the account. Update the saved password on your other devices, or remove and re-add the account, and the lockouts stop.

Can my admin unlock the account?

Yes. A password reset from the Microsoft 365 admin center unlocks it straight away, with no waiting. See step 03.
