I am having an issue with Kerio Connect 9.0.1 and Apple Calendar, El Capitan, 10.11.3
When I try to edit a single instance of the event I get:
Calendar was unable to save changes to Staff Meeting.
There was an internal error attempting to save this event. The changes made were not saved.
This is what I see in Console:

I am able to edit the event just fine in Webmail. Users did not have a problem prior to 10.11 as far as I know.
