Sorry the cut and paste didn't work for you.

Try this:

Create a temporary user in Exchange for her. That's what I do, always have one temp user account to test to/from.
Set up her workstation (Outlook or whatever you use) for that temp account.
See if she can get email after you've sent her a piece or two.
Then have her email someone else.

If that works okay, then her account is corrupted.
