I'm having the issue where people are receiving NDR's when creating calendar entry's. Apparently this is some kind of outlook issue created after a delegate is removed but it's functionality still remains. I found this MS article on how to remove the stranded delegates when using exchange. Problem is things are different with scalix so not all the steps are the same. Was wondering if anyone has fixed this issue with scalix.
This is the MS article I'm talking about http://support.microsoft.com/kb/253557
