The exception is caught in active sync code and the offending key is removed. If this happens often, you should enable the synclog and provide a log of the sync when this occurs.

Well, it can't be the exact same thing, because the logice that outputs the 110 status code is no longer in the code. Please post a new log showing what is going wrong now. Also, exactly what do you mean by "multi-user support"? Do you have two activesync accounts for two different users and this is the only time this error happens?
