Is there any way to change the internal autodiscover service to use an external address instead of an internal one? I'm moving my organization froma .com to a .org domain and we just got a shiney new UCC for the mail server. I specified the .org domain names, and id much prefer to use the external lookups for outlook to connect than the internal one since 75% of my users are on laptops.

You could change it, but if the clients are members of the domain they wouldn't use the URL - they get the information from the domain. Autodiscover when the client is off the domain uses set addresses based on the bit of the email address after the @ sign - so if you are using domain.org then autodiscover.domain.org needs to resolve to the correct place - and be in the certificate, unless you are using SRV records.

This Technet article explains how autodiscover works and covers both and external internal clients. http://technet.microsoft.com/en-us/library/bb124251(EXCHG.80).aspx Simon.Simon Butler, Exchange MVP. http://blog.sembee.co.uk , http://exbpa.com/

Hi, Of course, you can do that as long as the certificate includes the name. Thanks Allen
