I had a user names Jane Smith (Domain\JSmith) and mailbox with address email@example.com
Jane went off on extended leave and came back married. Through some admin mistake, she created a new AD account (Domain\JClark) and mailbox with address with firstname.lastname@example.org
Problem is, she's now recv'ing email at both addresses. She wants to use the new AD account (Domain\JClark) but with the old email address (since that's what all her business contacts know), although with the email@example.com address as some sort of secondary for a short amount of time.
I also need to merge the contents of the old mailbox to the new one.
What is the best way to do this? She recv's both internal and external email.
