I began a transition from Exchange 2003 to Exchange 2010 today. At the moment nearly all of my users are still on 2K3 (save for a few test accounts on the 2K10 server.) As best as I can tell everything is working fine - mailing is flowing in all directions.
I have a godaddy wildcard SSL certificate. It is in use on the 2K3 server. When I open OWA (2k10 sever) there is a Certificate error.
The security certificate presented by this website was not issues by a trusted certificate authority
On the 2K10 server there is also an error which I think is related:
EventID 12014: Microsoft Exchange could not find a certificate that contains the domain name mail.xxx.com in the personal store of the local computer...
I thought I could just export from 2K3 then import to 2K10 (as godaddy suggested) but that didn't work for me.
Under server configuration on the 2K10 server, two certificates exist: both as self signed and "valid for exchange server". The CN is listed as the server name but I am thinking that should be "mail"?
I am not sure where to start. I made have messed this up when I got slightly panicked earlier when we couldn't send email (I fouled up the send connector). Maybe I need to start over (the certificate part)?
