Allow data connections option not working? William Hudson 01-18-2008

 I am using Windows Vista and a PDA with Windows Mobile 6 Pro. In the Windows
Mobile Device Center Settings for the connection with my PDA, I have checked
the 'Allow data connections on device when connected to PC' option. However,
the PDA always refuses to synchronize with my Exchange Server (which is does
via WiFi when it is not connected to my workstation with a USB cable) in
spite of this. Have I misunderstood the purpose of this option? Is there a
way to get the Microsoft Exchange and Windows PC portions of my PDA
ActiveSync to synchronize at the same time? Currently, Exchange will
synchronize when the PDA is *not* connected to the PC and the Windows PC
(but not Exchange) will synchronize when it is.

Regards,

William

It took me a long time to get this to work, and finally required a registry
hack in the Activesync keys that I'm sorry I don't recall the details of,
but found it at xda-developers.com.

Yep, however, it appears (with the reg hack) to use the PC's internet
connection, not the GPRS connection on the device to sync with the Exchange
server.

Proxies can also be a problem. IIRC, when connected to the PC, any mobile-
phone data proxies are ignored, which causes me some trouble since my data
plan (from T-Mobile USA) connects through a specific T-Mo proxy. Maybe
that's why my Exchange Server updates through my PC's pass-through internet
connection.

That's the one- I'm sorry I didn't look it up for you myself, but I had
saved it in a .txt file on my PC, and posted my reply (like this one) from
my WinMo phone when away from the computer.

Nice find- that's certainly easier for the regedit-phobic!
(Of course, none of this discussion addresses the REAL issue of why a
registry hack is needed to enable a feature the device is supposed to have
in the first place!) ;-)
