I am working in an Exchange 2003 environment with multiple SMTP domains. A number of users need to be able to send email from either SMTP domains.
User A has a primary SMTP address of email@example.com, however he also wants to send an email out from a different SMTP which is specified in his AD E-mail address list firstname.lastname@example.org
I attempted to facilitate this by adding a new User record into AD called User A (Company2) and assigning that user with the email email@example.com and then giving the original User A full access to the new User A (Company 2).
This works to a degree. Some internet recipients receive the message from firstname.lastname@example.org whereas Outlook based internet recipients receive the message From email@example.com On Behalf Of firstname.lastname@example.org
I need a solution where ALL recipients will see the sender as email@example.com and preferably without a second record in the address book.
Any suggestions greatly appreciated.
