Sync Windows Mobile Outlook Contacts across 2 Exchange servers

Turns out it's not so hard to sync Outlook Contacts on Windows Mobile 5 (WM5) across 2 Exchange servers.

What:
I run my personal Exchange 2003 at home, and the corporate Exchange 2003 system at the office. Since these are completely separate organizations I want to keep my just my contacts in sync at home and the office. I don't really want the office mail on my PDA, but the calendar is nice there.

WM5 and all previous versions I've used wouldn't allow this. But, with 1 registry tweak it's possible in WM5.


Set the following key to 1 (default is 0):
[HKEY_CURRENT_USER\Software\Microsoft\ActiveSync\EnableNonLocalCrossPollination] = 1 (DWORD)

So, in summary here's what I'm syncing using ActiveSync 4.2.


Home PC
Contacts (shared) Only allowed after enabling registry change.
Notes
Favorites
Files


Office PC
Notes

Office Exchange Server
Contacts (shared)
Calendar
