Having problems with Microsoft Outlook 2007

When I load Microsoft Outlook 2007 I am getting this Note in the middle of my screen:
Internet Security Warning

The server you are connected to is using a security certificate that can not be verified
the target principle name is incorrect.

It has View certificate

When I view the certificate it shows the following:
Issued to: Platinum.ownmyserver.com
Issued by: Platinum.ownmyserver.com

Valid from 12/28/2013 to 12/28/2014

It ask me to select yes or no to continue using this server.
It won't no anything if I select NO
If I select yes it go's away until the next time I load Outlook

Next time this happens, in the alert box, click View Certificate.

Then click Install Certificate, then browse to and select the Trusted Root Certification Authority store and click OK.

Click next/OK/Yes as appropriate to all remaining prompts (including the original security warning prompt) and the warning should disappear next time you open Outlook.

Outlook is uptodate,
I have no idea of what San is, This has always worked before.
I don't use 110 I use 995 for pop3 and 587 for smtp.
I have to use  This server requires and encrypted connection(SSl
And the connection is TLS

I use centurylink for my internet service

I am beginning to think it might be a virus somewhere

When I view the certificate it shows the following:
Issued to: Platinum.ownmyserver.com
Issued by: Platinum.ownmyserver.com

 When I can not find it to delete?
