Hi,
We use Exchange 2010 Standard. We have one mailbox server and one hubcas server. I am posting here, if this is not the suitable place, please move it to the required forum.
There is no edge server.
Sometimes we have mails stuck in our mail security gateway.
I also get below errors in event logs.
Event 9213
A non-expirable message with the Internal Message ID 15805706 could not be categorized. This message may be a journal report or other system message. The message will remain in the queue until administrative action is taken to resolve the error. Other messages
may also have encountered this error. To further diagnose the error, use the Queue Viewer or the Exchange Mail Flow Troubleshooter.
Event 8010
A message with the Internal Message ID 15593265 was rejected by the remote server. This message will be deferred and retried because it was marked for retry if rejected. Other messages may also have encountered this error.
We have journaling enabled on databases.
Please let me know how do I find the root cause of this issue.
