UD Exchange Online: Unable to Log In to Outlook (Desktop or Web-Based)


Unable to log in to Outlook

If you are unable to log in to Microsoft Outlook, try the following:

  1. Verify that you are using your full UD email address as your username.
  2. If you're not in your office, try opening Microsoft Outlook on the Web (OWA).
  3. Verify that the caps lock on the number keypad is turned on. If you use the keypad to type in a password that contains numbers, your password will not be entered correctly.
  4. If you can't log in to OWA or Microsoft Outlook, you may need your password reset. Contact the IT Support Center.
