Auto Discover with different idomains question

My mobility servers have the same name inside and outside but our email addresses are different.

For example, our mobility servers are but our email addresses are, and and these users are spread across multiple mobility servers without regard to email address or organization (all in a single GW system).

Can I use auto discover with this setup?


  • Hi Al,

    I am working on the same type of configuration. Though I only have one Mobility server. I have set up the correct DNS entry. I used the SRV record to point to the A name of our mobility server. I then put a wildcard certificate in place using the TID about doing so with Mobility.

    The one issue I have is that the autodiscover/Mobility Service seems to return the Exchange Server name based on the domain name in the email address. So the user enters and auto discovery kicks in, passes through the correct username, password, but in the Exchange Server where out should be place it instead places just the domain from the email entry - - which does not resolve to our mobility server.

    This is very similar to your setup and how your mobility DNS entry does not match your email DNS entry. I would think this would be normal for many locations.

    I tested my autodiscover setup with the recommended Microsoft test site. The site reports that it autodiscover is working, it can locate my, confirm it's SSL certificate is completely valid, and connection are allowed on port 443.

    Does anyone out there know how to have autodiscover from GMS 2.0 return the correct Exchange Server address to a client?
