Hello,

i am currently trying to configure the Hybrid Agent Public Preview and i am always getting the following error in step 8d. (described here: https://docs.microsoft.com/en-us/exchange/hybrid-deployment/hybrid-agent#installation-steps) with the following error:

Is anyone facing the sam issue or has got a solution for that? Maybe it is a temporary bug caused of the preview?

Sounds like traffic to outside is blocked (firewall, outbound proxy) or other misconfiguration as the agent complains the request is sent, but it never receives a response within before timeout kicks in. What happens when you enter the URL in IE/Edge on the system, https://<That GUID>.resource.mailboxmigration.his.msappproxy.net/EWS/mrsproxy.svc

@Michel de Rooij  facing the same issue, my exchange instance is in Azure VM, and accessing https://cd8c452d-fa1f-4227-b58a-b21487d00062.resource.mailboxmigration.his.msappproxy.net/EWS/mrspro... says permission denied.

for office 365 I am using cloud only global admin.

Is that response coming from backend (authentication issue) or somewhere in between (blocked by or not authenticating against proxy, etc)

@Mohkam 

Estou com o mesmo problema como você resolveu? 

The remote server returned an error: (400) Bad Request

@Andre Luiz Silva 
we had to create a support ticket and some other engineer worked on it. It was resolved by ms support. I am sorry I am not aware of the solution.

[#7]

I had the same error when trying to create a migration batch. It appeared to be the credentials of the account that used to create the Hybrid endpoint. After updating the Endpoint credentials it worked without any errors. @Mohkam
