Outlook Autodiscover pointing to wrong URL

Hi Everyone,

I am having an issue with some users receiving an message looking for the autodiscover at the wrong URL .

Our setup is an SBS 2011 with Exchange 2010. The Exchange server has two accepted email domains (domain.ie and domain.co.uk). The primary is the domain.ie account. There is also two seperate websites for both the .ie and .co.uk (hosted externally). The domain.co.uk email users sometimes receive a message about the Auto-discover looking to domain.co.uk web site for the Auto-discover.

Just wondering should I create an external DNS record on the domain.co.uk (autodiscover.domain.co.uk) and have it point to the Public IP Address of the server/ exchange server (CAS). Also the SSL certificate in use is a single domain remote.domain.ie should this be different?

Any input would be greatly appreciated,

If you don't have Autodiscover.example.com on the SSL certificate, then you should ensure that Autodiscover.example.com does not resolve anywhere internally or externally.
Furthermore, with some hosts, you will find that example.com/Autodiscover/Autodiscover.xml (ie no host name at the front like www) will work, because one of the hosting packages uses it. You need to get the host to disable it.

Internally it doesn't matter, as they should be getting their information from the domain, using a value that SBS populates during the setup of the server.
