I am wanting to know the best way of achieving the following
I have a User in exchange which has a email address of email@example.com in which he sends out of
He also wants to have firstname.lastname@example.org email address in which i know i can just setup an alias for him on that account but the third thing he wants to be able to do is to send as email@example.com instead of firstname.lastname@example.org sometimes when the circumstance arises.
I am wondering what the best practices is to make this work
I have played around in the past of making Distribution groups and sending that way, and i also know I could just make him another email box all together but what will take another licence and i am hoping there is another way of doing this
