I have an exhcange server configured to work with my AD domain i.e.(firstname.lastname@example.org) I have another domain name xyz.com that I want to be able to send/receive e-mail from. (email@example.com). I have configured exchange to allow thsi domain and if I send e-mail to firstname.lastname@example.org, I receive the e-mail.
How can I SEND e-mail from email@example.com and RESPOND to e-mail sent to firstname.lastname@example.org and it show to be FROM email@example.com.
1. I can receive e-mail sent to firstname.lastname@example.org. If I reply, it is sent FROM email@example.com
2. If I start a NEW e-mail and change the FROM field to firstname.lastname@example.org I get an error from Exchange... "You are not allowed to send this message because you are trying to send on behalf of another sender without permission to do so. Please verify that you are sending on behalf of the correct sender, or ask your system administrator to help you get the required permission. "
can anyone help?
