I'm trying to set up TLS for the POP3 server in the Exchange CAS role.
I purchased a cert from NameCheap, and the CA path is fully trusted, and installed it within the Certificates MMC snap-in without any trouble.
However Exchange 2010 doesn't seem to like it: I see this in the event viewer:
Event ID: 2007 Source: MSExchangePOP3 A certificate for the host name "mail.mydomain.net" couldn't be found. SSL or TLS encryption can't be made to the POP3 service.
...despite the fact that such a certificate does exist:

I've started the server (and services) numerous times. I don't understand why it doesn't work.
