The Autodiscover service is a mechanism that can do several things.When you first launch your Outlook 2007 client (Outlook 2007 required for Autodiscover access), it will search Active Directory for a Service Connection Point (SCP) record.
Again, don’t forget that it’ll get a list of all SCPs for all CAS servers in your environment and use one at random.
You can set it to any FQDN really including your OWA URL (owa.perhaps) as long as that name is on the certificate.
You can use the Net BIOS name in the certificate, but you will be exposing your Net BIOS name to internet users.
Some may think this is a big deal while others don’t care too much.
Personally, and this is just a personal opinion, is who cares.
This SCP will return the Autodiscover Internal URI FQDN in which this client should contact the Autodiscover service.
