This is 100% not true.

This is a limitation of the ActiveSync protocol, not our  
implementation of it. The protocol is only designed to handle the  
user's "main" exchange calendar. We attempt to improve upon this  
limitation by multiplexing the calendars together into a single  
calendar stream seen by the client. The result of this, is of course,  
that while you can see all the calendars, since they appear as a  
single calendar to the device, you can only create an event on your  
"main" kronolith calendar.
