ok… fairly simple

 

you are in powershell running test-outlookconnectivity and you use either tcp or http as the protocol

and you get a failure for the RFRI and NSPI part….

i checked everywhere on the web and could not find the answer

i checked the autodiscover uri and that the databases in use had the right client access server set

but i did not check the exchange address book service!

so lesson learnt first thing first CHECK that all automatic exchange services are started and running ok
