Exchange Certificates

tmartin40 asked
I am currently running Microsoft Exchange 2007 and connecting to it using either Outlook 2007 or Outlook 2010.  There is a certificate installed on the Exchange server that validates when Outlook connects to it.  I am, however having a problem when my users try to connect to webmail.  They are connecting using https://... and are receiving a certificate error when they connect.  I thought I was doing the right thing and purchased an SSL cert from Network Solutions.  Once it was installed, the webmail error went away but now Outlook is throwing errors.  The only thing I can think of is that the server name depending on how you connect is different (Outlook=SAA-EXG, and webmail is https://mail.rpsalaw.com/owa).

Does anyone have any ideas on how to correct for this?

Hi Martin,

What is the error you are getting now in outlook?

I think the answer for your query is present in microsoft KB  940762

Outlook is erroring because of the internal autodiscover is not properly configured.

If you only have mail.rpsalaw.com in your certificate, you need split-dns and configure the SCP record with the same value.

Check http://www.howexchangeworks.com/2011/07/how-outlook-2007-clients-connect-using.html and http://www.howexchangeworks.com/2011/07/service-connection-point-scp-in.html

Or amend the certificate with an internal url that can be used as the "AutodiscoverServiceInternalURI"
