CMG - Exchange anot able to query availability information

Hello,

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?

BR,

Ferenc
