I have configured CMG to work with Exchange Hybrid environment. (Exchange is 2016 on-prem)
I need to follow the scenario #7 (single namespace with Exchange Hybrid) for my case for Free/Busy infomration exchange between GW and Exchange/EXO.
Exhange is not able to query any user FB information from GW.
I have checked the autodiscover URL from Exchange server.
It is working without any issue.
Any idea where to start debugging of this issue?
