I havent checked the newer versions but the older ones do not seem to
support loose routing.
The only way around seems to be either to not use Record Routing at all,
or use strict routing.
For MSN, we configure our proxy not to loose route. Dont know if this
feature has been addressed in later versions.

Hi there,
It seems that the Microsoft Messenger response to a loose routing
Record-Route with a 400 Bad Request. Did anybody else have such an
experience?
