I have installed Intellisync on 4 blackjack users and 2 of them have had
99% of their calendar deleted. The Intellisync log simply says:

Calendar (181 deleted, 5 sent) followed by a few
Folder is locked. Retrying Synchronization.

I have no clue what is going on here, esp since I have been running this
with Treo's for almost 2 years now. I know of no reason this is
happening and no way to get these calendar items back.

This is on a GW7sp3 fully patched Server (NW6.5) and GMS 2.04

Any guidance would be GREATLY appreciated.
