Using Windows Mobile 5 Devices, Exchange 2003 SP3 Push Mail and Checkpoint R55 NG

[Boonsa]

Phewph! Even the topic for discussion is heavy going!

Basically what I have is:

Nokia IP130 Enforcement Module
Windows 2003 Management Server
MS Exchange 2003 SP2 (push mail enabled)
02 XDA Exec and Xda Mini S both with updated ROM versions to enable Push Mail.

What I want:

To get the mobile devices to talk to the Exchange server and sync on a timed or demand basis.

Current Scenario:

Our front end Exchange Webmail server is accessible via HTTPS, https://ex1.esriuk.com, it prompts PC dekstop/laptop users to accept a certificate generated by our internal CA.
You are then prompted to input a username and password (a combination of domain logon and Checkpoint username).

When we attempt to "sync" our mobile devices using ActiveSync, the mobile devices attempt to connect to the Webmail server but produce an error message:

"Support Code: 0x80072f17"

How can I achieve this with our mobile devices?

That doesn't look like a Check Point error. Is an error from the firewall or one from the Exchange server?
