We are in the beginning phase of migrating from Exchange 2010 to Exchange 2013. When I login to the exchange 2013 admin console and navigate to servers it does not show me any of my servers. When I navigate to mailflow-receive connectors I receive a 500 error. When I run the powershell command to get-receiveconnectors it shows me the correct exchange 2013 connectors. I checked IIS and the permissions appear to be correct. Not sure where to look to resolve the issue.

What do you see from the Exchange Management Shell when you enter Get-ExchangeServer?
