I just enabled OMA on my Exchange server.  I set up my PDA to use the Exchange Active Sync, but when I try to sync, I get the following error:

"The Security Certificate on the server is invalid.  Contact your Exchange Server administrator or ISP to install a valid certificate on the server.

Support code:80072f0d"

I DID import the certicate on my Exchange Server (we've been using SSL for years) to my PDA by following the steps listed here:

http://www.microsoft.com/technet/itsolutions/mobile/deploy/msfp_b.mspx

It worked perfectly and the Certificate shows up on my PDA's Root listing.. but I still get that error when I try to sync!

The PDA is a Dell Axim 51v using WM5 with Exchange 2003 SP2 on the back end.

Is the certificate a home grown or commercial certificate?
Did you import a root certificate, or the certificate off the web site?

I followed the instructions listed in the URL in my first port.  It had me make some XML file and copy/past the cert info that was in my .CER file on the server then create a CAB and install it on the PDA.  Look at that URL.

The Cert is commercial from Equifax Secure Global eBusiness CA-1

I am well aware of what the URL states.

I have written my own instructions based on a similar technique because it doesn't actually tell you what certificate to use - whether the SSL certificate the supplier issued or their root certificate.

For maximum success, you should use the root certificate from the certificate supplier - not your own certificate.
Your own certificate is not a root certificate, so even if it is in the root certificate store, the Windows Mobile device will not look there.

Download the root certificate for your certificate from this page:

Then repeat the process.

Once I had the correct cert from that site you gave, everything worked perfectly!  Thank you.
