When Access is Interrupted: Solutions

⚠️ Incorrect or forgotten password

Cause: Typographical error in credentials or memory lapse.

Solution: Carefully re-enter your email and password, checking for typos or ensuring the Caps Lock key is not active. If your password is forgotten, use Microsoft's account recovery page to reset it. You'll need to verify your identity through a backup email or phone number.

⚠️ Account temporarily locked

Cause: Too many unsuccessful login attempts triggered a security lockout.

Solution: We know being locked out is stressful. Your account may be temporarily locked as a security measure. Wait for a period, typically a few minutes to hours, before attempting to sign in again.

⚠️ Persistent login issues or loops

Cause: Corrupted browser data or cached credentials interfering with the authentication process.

Solution: Try accessing Outlook 365 using a private or Incognito browser window. If this works, clear your browser's cookies and cache for all time. For desktop applications, clear any cached credentials from the Windows Credential Manager related to Microsoft Office, then restart Outlook and sign in again.

⚠️ Service not available

Cause: An ongoing service outage or maintenance on Microsoft's end.

Solution: Check the official Microsoft 365 service health status page. If there's a reported outage, all you can do is wait for Microsoft to resolve the issue.

If you are using a free email service like Outlook.com without an active Microsoft 365 subscription (Basic, Personal, or Family), you might see advertisements within your inbox.
