I have an SBS 2008 server migrated from SBS 2003. I have a GoDaddy class2 cert installed as "mail.mydomain.com" Everything works correctly with Outlook internally, RPC/HTTPS and POP3. The problem is IMAP does not bind to the correct cert. When I try to connect to the Exchange 2007 server via IMAP the certificate is showing as the SBS self signed cert setup during the migration.
The self signed cert and the GoDaddy cert have exactly the same FQDN.
I have run the command <enable-exchangecertificate -thumbprint "thumbprint_of_GoDaddy_cert" -services “IMAP,POP> from EMS and still the cert is incorrectly bound to the SBS self signed cert for IMAP, POP works just fine.
I have tried changing the cert to the self signed cert stopping and starting IMAP svc and changing back to the GoDaddy cert stopping and starting IMAP etc..
What am missing?
