I am observing errors in pykolab.log file:
2016-11-16 09:02:00,558 pykolab.wallace ERROR Expunge resource calendar for cn=Besprechungsraum Forest 0-56-R2,ou=Resources,dc=genua,dc=de (shared/Resources/<mailbox>) failed: TypeError("can't compare datetime.datetime to datetime.date",)This is because parsing event wallace gets event end time as a date, not as datetime instance.
Of course, the first question is how come there are events which have end date without time, but I suggest to add yet another try and except clause to wallace code:

It is also possible to try to convert datetime.date to datetime.datetime before checking if the end of event is more than 100 days ago.
