If this test isn't successful, the local computer may be unable to connect to the Autodiscover service. The following are some common reasons that may cause this issue:

• 1. A local firewall blocks Outlook from connecting to the Autodiscover service.
  2. Outlook may not be running the latest updates.
  3. Local Autodiscover-related registry data may be present.
