Autodiscover

Autodiscover is important. To check autodiscover services you can hold down ctrl whilst right clicking on the Outlook icon in the system tray and choosing "Test E-mail configuration"

You can also check by surfing to https://tripany-ad.local/autodiscover/autodiscover.xml and seeing if you get a response.

You also need to make sure you have an SRV record set in your DNS.
