killerbecks -> SBS Exchange 03 - iPhone - Activesync (29.Sep.2008 7:55:12 PM)

Windows mobile devices work fine. OWA works fine.
I have been through Dr. Shinder's guides and rebuilt IIS, CA, etc... to no avail
When looking at the W3SVC logs on the Exchange server = no data
When looking at the Web logs on ISA = one line connection attempts

Here is a capture from the external side of ISA - Any help would be greatly appreciated

killerbecks -> RE: SBS Exchange 03 - iPhone - Activesync (29.Oct.2008 5:58:04 PM)

Found the answer:

Basically, the ISA 2000 firewall server filters the Activesync headers and doesn’t forward all necessary data to the iPhone. The fix for ISA 2000 requires BOTH the latest ISA service pack and a registry change to allow all the communcations options to be passed via Activesync:

Once the ISA 2000 Service Pack is installed, set the registry key DWORD HKLM\System\CurrentControlSet\Services\W3Proxy\Parameters\PassOPTIONSToPublishedServer - Data value to 1, and reboot the ISA server.
