Autodiscover for a different mail address space
Posted on 2009-06-30
i could use your thoughts on the following situation:
we have an exchange 2007 platform that has a public URL of mail.mydomain.com, but have user mail addresses under a sub domain, email@example.com.
in order to get autodiscover working, will i need to DNS records for autodiscover.sub.mydomain.com, and of course publish the site, with a valid cert, for that url as well...or could i perhaps use a forwarder in DNS so that when they enter their mail address, it looks for autodiscover.sub.mydomain.com which points them at autodiscover.mydomain.com, which returns the target IP and so eventually resolves against autodiscover.mydomain.com or mail.mydomain.com
hopefully that makes sense? essentially i've published the autodiscover.mydomain.com with a cert for it, and then tried to use autodiscover and of course it wont resolve to a valid exchange server because the users mail address is in a sub domain...so presumably its looking for autodiscover.sub.mydomain.com...which i have not published, and i need to find a way around this.
