Hello everyone.
We had a very weird error this morning on our Exchange 2013.
We were not able to receive email from outside, but we were able to send to the outside.
I was doing some testing with an outside account and I noticed that when I sent an email from outside(google) to the exchange, in the Delivery Report, you can see the email but at the bottom there was a message saying.
The message couldn't be delivered.550 4.3.2 QUEUE.TransportAgent; message deleted by transport agent
The message never reached my mailbox.
We rebooted the server and the mail started to flow, but all those test email and of course the real email that was coming in at that time is lost.
Does anybody know what this could be?
Any guidance will be great. Thanks in advance.
Jack.
