I performing cross-forest migration from Ex2003 to Ex2010, and I configured Shared SMTP namespace but when I send e-mails to a mailbox that migrated from Ex2003 to Ex2010 forest, I got the following error in E-mail:
A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. (NDR 5.4.6)
How can I solve this?
Thanks.
