Todd -


Who is your Certificate Authority and what type of Cert is it?


Windows Mobile devices recognize only a small # of Certificates
(especially older Windows Mobile devices).  If you are having issues
connecting, the issue most likely is that the Cert you are using on your
front end is not an accepted one for Windows Mobile devices.

See this: http://support.microsoft.com/kb/915840


Or this:


To verify, you can request a 'trial' certificate from Thawte.com (SSL
123 type) and deploy.  This is a fully functional cert for 30 days that
is accepted by all Windows Mobile devices without having to force the
device to accept it and the authority.


What is your OWA URL?  

good luck.

Subject: [ExchangeList] Problem setting up Microsoft Exchange Active

I'm have difficulty setting up Exchange ActiveSync in a single Exchange
2003 setup. The Exchange server is front ended by ISA2006 SE. I have
read and used the article "How to Publish Microsoft Exchange Active Sync
with ISA Server 2006" by Marc Grote. The error that the mobile device
gets is "The security certificate on the server is invalid. Support Code
: 0x80072f0d". I have the OWA certificate installed on the Exchange and
ISA servers since Sept 2007. OWA has been working fine since that time.
I think my problem is related to SPN for HTTP/owa.all-mode.com. Should
this be on the Exchange or ISA server?

Any help is greatly appreciated.
