Hi all,
I'm trying to setup a hybrid with Exchange 2010 (14.3.513.0) and I get the error "HCW8078 - Migration Endpoint Could not be created" at the end of the Wizard.
If I run Test-MigrationServerAvailability from the EOL Powershell I get the following error:
RunspaceId : 537c3401-d723-40f8-a9c9-9a82eeff5fbd
Result : Failed
Message : The connection to the server 'remote.xxxxxxxx.com' could not be completed.

TestedEndpoint :
IsValid : True
Identity :
ObjectState : New
I have confirmed ports are opened on the firewall, in fact, I can see the connection coming in through port 443.
I've also confirmed that the MRSPROXY is enabled, with Basic, NTLM, WindowsIntegrated and WSSecurity authentication set to true.
I can access https://remote.xxxxx.com/EWS/mrsproxy.svc' from outside and get the prompt to enter the credentials, which work.
I tried resetting IIS.
I also found that the computer object had the adminCount attribute set to 1, and that was part of the Cert Publishers security group. I removed the object from that group, set the adminCount atribute set to 0, then restarted and the attribute was set back to 1 automatically.
Any ideas?
Thanks
Gabriel

I am having exactly the same problem. It was working about 2 weeks ago, I added the MRS Proxy at that time, performed a test migration without issue, then waited for the customer to be ready to start migrating, then when we were going to do the first migration batch, it stated that our migration endpoint was not functioning. Now I cannot get it to add again. I have done the same steps and I see this adminCount set to 1 on my server too. I removed the policy certificate authority from the server and removed it from the Cert Publishers group as well. Still not able to add a migration endpoint on this server. Have you had any success in resolving this?

@cjm-1993 just wait until the service health issue has been fully resolved and it should work normally again. Watch this advisory for updates:

Hope this helps!
