One of our users is getting the message "this e-mail message cannot be delivered to XXX because the e-mail address is no longer valid" .  I logged on to her computer, started addressing the e-mail and when the staff name came up I deleted it.  Then I used the address book to find the staff name.  After I selected it, the same message was display that it was no longer valid.  I sent a test email from my Outlook 2010 account to the same user and it worked fine.

I'm not sure what you tried already, but see below:

Link 1 - For the last post, it mentions updating the Global Address List. See here for more info on that.

A user here mentioned resetting the username. See this Microsoft link for more details.
