Thanks for signaling this error. I am aware of it, although I don't think it should have bad consequences (at least I think...). But I will see if it is possible to get it fixed.
Could tell me which operating system you use on your desktop ?
Which kind of error do you see in ActiveSync/WMDC window ?
Do you see an alert window while synchronizing ?
Thanks.
If you see no error in ActiveSync window, it could mean that no item category is selected in ActiveSync options window. Did you select "cards", "events", "tasks" or "mails" in ActiveSync window (not Outlook categories like "contacts", "appointments", ...) ?
