Mail routing problems between two sites


  • Dear Concern,

    I have two site Site A (DC site) and Site B (DR site) and 3 Exchange server 2010, 2 are in Site A and 1 is in Site B. When Site A users send mail to site A users it passes to Site B Exchange server and mails are queued in submission queue and give a error:

    Failed to process message due to a transient exception with message The user and the mailbox are in different Active Directory sites.

    I also enable site affinity and DR site exchange shows in Site B.

    what's the cause of this internal mail routing issue.
