Hi,

I haven't attempted to understand all of what you wrote (yet), but I do have 
one suggestion: try to reproduce the problem with a modern client (10.8.x). If 
the problem reproduces in 10.8, a bug should be filed along with some 
supporting data. If the problem does *not* reproduce in 10.8, that suggests the 
problem was fixed some time since Snow Leopard (which is not hard to imagine). 
In this case, the best course of action would be to upgrade the clients. It 
would most likely not be worthwhile to pursue a fix for 10.6 clients.

As an aside, be aware that your question is about OS X Server, and this email 
list is for the open source distribution of Calendar Server (which does not 
involve OS X Server). The difference is that there are official support 
channels available for OS X Server, while support for the open source 
distribution is provided as is, with no warranties expressed or implied, etc 
etc :) I'm not trying to send you away, just merely to set expectations.

HTH,
