I've attached two events. The first called Outlook-Invite.ics was sent 
from an Outlook account to a Kolab account. The event was accepted which 
generated the second attachment called Kolab-Accept.ics. As mentioned, 
this second event created by Kolab does not work with any Outlook 
version I've tried, it shows up as an attachment and the recipient 
cannot be accept or update their Outlook calendar with it. The same 
Outlook behaviour happens if the event is first created in Kolab.

Thanks.
