We just obtained a wildcard cert from GoDaddy and successfully imported and assigned the iis and smtp services to the cert.
The cert is *.domain1.com and our internal domain where Exchange is hosted is *.domain.local.
Now OWA and ActiveSync work without displaying the invalid cert error, but internal Exchange users receive an invalid certificate error as it is using the GoDaddy certificate and therefore lists as exchange-server.domain1.com instead of exchange-server.domain.local.
How do I address this? I've used wildcard GoDaddy certs in the past successfully with Exchange 2007, so it should be possible without using a UCC cert.
I simply want to be able to use the GoDaddy cert for OWA and Activesync (and pop and imap would be nice too), and the self-signed cert that came with Exchange 2010 for internal Outlook clients on the domain. It seems that I can only assign IIS to one of the certs, as the thumbprints get overwritten, so I'm not sure what to do.
