Microsoft Exchange Self Signed Certificate how to install on local Outlook, security certificate invalid does not match name of site

I recently had to re-install SBS2008 at a client site. I can't remember how I setup the self-signed certificate authority on the server in order for Outlook to correctly work without the attached screen shot pop-up. I have tried 6 ways from sunday to install the certificate. E-mail works, OWA works, I just need this pop up to go away. I'm hoping someone more versed in Certificate Authority and exchange could help.

thanks,
Ryan

Export the root certificate of self-signed certificate and install on on client.

Depending on the size of your organization a gpo could work for you

So, I did this once with one of the certificates. It installed just like the webpage said it would. It's almost although I have an "extra" certificate lingering around. Like I said, exchange is working. How can I trace back the certificate that's bogus or un-necessary?

I have attached a copy of the certificate that complains when launching Outlook. I have also attached a screen shot of the "good" certificate I have already successfully installed. Where does the extra one get stored. I do not see it on the server under the Certification Authority -> Issued Certificates....

See the attached image

The certificate should be present in the Personal -> certificates folder

It should then on EVERY client be installed to the folder where the arrow is pointing.

No, still questions. I try and store there on every local computer, however; it doesn't get stored. Every time I launch outlook, it pops up again.

I had to google how to do it in Server 2008, but the answer was to push it in the GPO. Thanks for the help!
