Critical - Exchange is down
Posted on 2011-05-03
I was having a lot of issues connecting to exchange 2010 with EMC and EMS - lots of authentication, access denied errors - spent about 30 hours trying to resolve it and it just wasn't happening.
So, I set up a new server, installed Exchange 2010. Everything seemed to be fine but somewhere along the line mail stopped being sent out. It's getting stuck in the queue with error message: 451 4.4.0 Primary Target IP address responded with: "421 4.3.2 Service not available"
It may have been a change I made on the send connector? Anyway, I don't remember what I changed and I need to get this back up and running.
My goal was to install exchange on the new server, then move everything over and decomission old server, but, obviously not happening - can anyone help with this?
