Could you please help?
Every time I sent to Distribution list or recipients I got a”
Delivery has failed to these recipients or groups:
Your message wasn't delivered because the recipient's e-mail provider rejected it.
I know why i am getting this error, because we migrated all users form one domain to the other and we switch off the old domain.
Question is : how do i search or find this user in AD or Exchange 2010 " firstname.lastname@example.org"
Is any script or GUI i can find the SMTP in Exchange 2010 and Exchange 2003
Thank you in Advance and your Quick response
