btw: It always helps to say which version of Kolab Server you have
installed.

You can, this is a typical consultant task to find a good solution for you.
Most of the time when our of our KK consultants sets up a Kolab Server
is spend finding and explaining a good email setup.
Especially for test settings and soft migration.
Every time it is a bit different because of the surrounding circumstances,
so it is hard to write a generic documentation for it, except what is there 
already.
In you case I suggest to take a look at:

The calender features usually involve sending and receiving email with 
iCalendar information inside, so it usually should be connected to an email 
system. Of course you can run both email systems (other one and the one of 
the Kolab Server). Usually it is best to integrate them , though.
