How do I troubleshoot Microsoft 365 sign-in issues?

Fix common login errors — wrong password, MFA issues, account lockouts.

Troubleshooting Microsoft 365 Sign-In

### "Your account or password is incorrect"

1. Use full email as username (name@company.com)

2. Check Caps Lock

3. Reset at aka.ms/sspr or ask admin

### Account Locked

Wait 60 seconds (smart lockout auto-releases) or admin resets via Azure AD → Users → Reset password

### MFA Not Working

  • Authenticator not generating codes: sync phone time (Settings → Date & Time → Auto)
  • Lost phone: admin deletes MFA registration, user re-registers

### Browser Issues

1. Clear cache and cookies

2. Try incognito mode

3. Try a different browser

4. Disable extensions

### Mobile Not Syncing

1. Sign out completely

2. Remove and re-add account
