Outlook Autodiscover vs Internal DNS – Exchange 2010

,

Hosting email for multiple domains can be complicated. Especially when all the hosted companies have their own internal DNS servers. This morning we had a customer who was getting a certificate error complaining that the autodiscover.domain.com cert did not match the name it was looking for. After using the Exchange connectivity tool (Test Exchange) We verified that from the outside everythihttp://www.acumenitsupport.com/wp-content/uploads/2012/10/www.testexchangeconnectivity.comng looked good. Once we got into the customers’ internal DNS we found a wildcard record for their outside domain (domain.com, not domain.local) that pointed to their webserver. Once we deleted this and created a SRV record that pointed them in the right direction for _autodisover, Outlook ceased to complain about the certificate because everything matched.

These sorts of issues can be the source of much wasted time and effort for an IT staff already overburdened with internal problems.
