I am new to exchange 2007, but urgently need to create a mailbox for user. This user already exist in AD.
From Exchange Management Console, I find Recipient Configuration > Mailbox > right click > New mail box and follow through to create the mailbox for my existing user, the mailbox created is under Email Adresses is email@example.com.
But I want to create the user under firstname.lastname@example.org.
To attempt, from the Email Addesses tab for the Mailbox property dialog, I "Add..." an SMTP email email@example.com and set it to default reply email. But when I send the from gmail.com to that email, exchange reports 550 user not found.
Also another aside, deleting that mailbox ALSO deletes my existing user!! That is totally irritating, how to avoid that?
