I wonder if someone could help me as a matter of urgency
Mail flow seems to have stopped on our Exchange 2013, I think the server might have rebooted itself over the night but I am not sure.
I've rebooted the server and all the services have restart, our mail is coming in from the barracuda email system and getting stuck in the local queue - I've sent test email out and its also getting stuck in the local queue
Internal Email appears to be flowing correctly
Running Exchange connectivity Analysis I get the following
Testing inbound SMTP mail flow for domain 'email@example.com'.
The Microsoft Connectivity Analyzer failed to test inbound SMTP mail flow.
