Hi,
We are using Exchange 2007 and it was working fine till today.
Today we are getting the following error message on the exchange server:
451 4.4.0 Primary target IP address responded with: 421 4.4.2 Connection dropped. Attempted failover to alternate host, but did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. And the emails are stuck in the queue.
I really need to solve this problem as the emails are stucked in the queue.
Can someone help me with this.
Thanks
