I have an exchange Mailbox Server, Alt-EXCH, that has a high number of messages in both the Journal Queue (30000) and the Mailbox Queue(8000). I believe the counts are high because of all the retries. And I found that the messages were not delivering because of a incorrectly configured network adapter. (i.e. the Secondary DNS was not configured properly for the TCPIP Static IP). The Secondary DNS ip has been corrected.
There is a second exchange Mailbox server, Primary-EXCH, that has been up and running for over two months with no issues.
The Alt-EXCH server was initially up for about an 1.5hours when the issue was noticed and then shut down. It was brought up twice more for no more then an hour at a time for troubleshooting purposes. So I cannot imagine a whole lot of email getting stuck in the queues.
Now that the DNS issue has been resolved I would like to fire up the ALT-EXCH server and let the Queues go through the delivery process. Is there any foreseeable issue with this action plan? Is there a better way to do this?
Please note - there are no DAGs involved on these servers.
