[SyncEvolution] MS Exchange and KDE synchronization: Colleague's calendar?

Hi, I tried the MS Exchange and KDE synchronization as described in the wiki. It works with my calendar, but I would like to see my colleague's in KDE kmail as well. Is there any way to do that? I tried to use my colleague's email address as user(a)example.com in the wiki and my username and password for "*workdomain\username*". But that gave me my calendar once again. Thank you for any help or hints! Stefanie (I'm not subscribed to this list, please keep me in cc)
