We have a user that just got married and we need to change her name (email) address to reflect her new name. What would be the best way to do this so they will be able to keep their mailbox (and emails contained), She needs to be able to still get emails to her old email address (for a period of time) as well as emails to her new email address. Basically 1 mailbox, 2 email addresses. We have exchange 2010 and obviously active directory on this domain. This domain is ONLY used for email so we don't have to worry about anything else other then email address and name.
