Sure. I copied them right out of the config guide and change the hostnames to the vip hostnames and added a valid exchange login to the monitor. Here is one example
GET /owa/auth/logon.aspx?url=https://mail.example.com/owa/&reason=0 HTTP/1.1\r\
nUser-Agent: Mozilla/4.0\r\nHost: mail.example.com\r\n\r\n
This is the response I get from the cli
