Hello folks...

A couple of months ago I've noticed I wasn't able to synchronise calendar items created on my Windows Mobile device, back to my Exchange Server 2003 SP2.

I couldn't find anything on the ActiveSync logs, but a few days ago I tried creating an appointment through OWA and got this message "The action can't be performed".

A search reveals this KB http://support.microsoft.com/kb/310440/en-us but after checking on my server I see the registry keys are already there - and correctly set.

Any other ideas?
