Autodiscover for a different mail address space

Hi all,

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, user@sub.mydomain.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.

If your DNS provider supports SRV records for the sub domain, then you can use that. Otherwise you will need to use autodiscover.sub.example.com. Many public DNS providers do NOT support SRV records.
Exchange treats it just the same as it would autodiscover.example.co.uk - same name of parts.

thanks Simon, thats all i need. we host our own public DNS, and i know we do support SRV records. Its replicated to an external DNS provider as well howevwer and i'll double check with them.

i am however somewhat curious as to how outlook 2007 will search for the relevant SRV record...as i say, surely it will search for a record for the users mail address space, which as mentioned is a sub domain of the actual published site.
Autodiscover SRV records method.
