Have setup the ews_response probe, the QOS_Exchange_Mail_Send returns a value that seems to be ok, but the QOS_Exchange_Mail_Roundtrip returns a negative value "-27". Is it a bug?
Anyone seen this behavior?

Usually this will be a time synchronization issue.
if the systems time is of you can see this easily.
If you make sure the systems are all using the same sync source
and still seeing this issue I would open a support case.
