I'm having trouble setting up autodiscover for our Exchange 2013 infrastructure. We have two domains, let's call them domain.co.uk and domain.com and both of these should be serviced by the same server, which is set up at mail.domain.co.uk.
Autodiscover on Exchange is set up correctly for domain.co.uk and the certificate that the Exchange server presents is a wildcard certificate for *.domain.co.uk. Therefore when you add firstname.lastname@example.org to one of our corporate mobile phones, it gets all of the user settings and correctly sets the phone up automatically.
Autodiscover for domain.com does not work under the same scenario. It reports that it cannot verify the account. If you enter the information manually, it works.
DNS is set up thus:
autodiscover.domain.co.uk 3600 IN CNAME mail.domain.co.uk
_autodiscover._tcp.domain.co.uk 300 IN SRV 0 0 443 mail.domain.co.uk
_autodiscover._tcp.domain.com 300 IN SRV 0 0 443 autodiscover.domain.co.uk
Microsoft's Remote Connectivity Analyser says that all is well. Can anyone shed any light on what I might have set up incorrectly?
Thanks in advance.
