I have a 3 year old Exchange 2010 server that is fully patched.
I replaced an expiring SSL cert with a new one. The new one is valid from 6/17/13 to 6/27/15 with the subject of mail.publicdomainname.com.
However, when I open up Outlook, it pulls up an expired certificate that is for publicdomainname.com. What's odd is that I don't have that invalid certificate anywhere, and it's not something I created as far as I can tell. I've deleted all other certificates on the server and left only the new valid certificate that expires in 2015. I've restarted IIS and the mxexchangetransport services.
Screen shot 1 and 2 attached are what I get when I open Outlook and connect to my Exchange server (from outside the LAN). That is the invalid certificate that I should not see and I want to replace with the valid certificate, but not sure where it's configured in Exchange Management Console.
Screen shot 3 is what I see from Exchange webmail. It shows my valid certificate. Screen shot 4 is the list of certs you can see from Exchange Management Console. Do you have any suggestions for where I should go to make sure that Outlook is using the right certificate? I've gone in and assigned all services to the proper certificate (screen shot 5).
Thanks in advance.
