ActiveSync: calendar strips future entries

[Tobias Brunner]

Hi,

It looks like events from the calender are deleted from the device if 
they are more than two months in the future.

F.e.: I've created an entry on the 22nd of June on my Nokia N9, this 
entry is now synced to Kolab an I can view it on my Roundcube calendar. 
Later on the entry is being deleted on the device, but stays on the 
Roundcube calendar.
Any idea why this could happen?

Cheers,
Tobias
