SBS2011 Remote Access/OWA Troubleshooting
Posted on 2014-04-14
We have a server running SBS 2011.
Today some of our Exchange services have become unreachable from outside the network. OWA doesn't load and users emails have stopped working on their phones/tablets.
Everyone inside the building (ie. on the local network) can send/recieve emails just fine. VPN and RDP still work fine also.
I have tried restarting IIS and Exchange services with no success.
I am also receiving this error when trying to access Exchange Management Console or Shell.
Connecting to remote server failed with the following error message: The WinRM client received an HTTP server error status (500), but the remote service did not include any other information about the cause of the failure.
Any suggestions on troubleshooting this issue are much appreciated.
