Hello,
I have been using Exchange server 2013 for a week on single box called EX.tom-af.com and everything worked fine. After a week I added another server (EX2.tom-af.com) with both roles on it for MBX and CAS (with round robin DNS) high availability. DAG is working fine, however, only some users getting long delay on delivery or even failure. I think they are those users who their messages are going through EX2.
Also, when I check on delivery report, I get this error message:
"Server EX.tom-af.com in domain tom-af.com encountered an unexpected error. Diagnostic information for this error: The message-tracking data on server EX2.tom-af.com had invalid data in column 12 for this message. Event "THROTTLE" will be ignored."
Can anyone tell me when which setting I should go through and make sure they set properly, so I don't get this error as well as delivery delay?
Thanks!
