Hi,
I have two Active Directory site like SiteA and SiteB. I have three Exchange server 2 for SiteA for DC site and 1 for SiteB for DR site. Mail flow is okay but when I move the 3rd Exchange in SiteB then mail starting go through the 3rd Exchange server and submission failed with error message "Mail routing failed User & Mailbox are in two different active directory sites".
Thanks.
