Received Email in Outlook Asks for OWA Login

I have a user with Outlook 2002 on Windows XP workstation. This afternoon for
some reason when she received email from one particular remote sender (who
works for us) who is using our OWA on her Vista machine, upon opening this
sender's email an OWA pop-up login window comes up even though she is in her
Outlook. It was working fine until this afternoon and we made no changes on
our Exchange 2003 server which is on Windows 2003 Enterprise server. I had
the sender send me a test message the same way and I received it fine within
my Outlook 2002.
For my receiver it is acting as if she is using OWA instead of outlook and
it is only from this one sender, all other emails she receives are opening
normally. Plus when she enters her userID and password like she would in OWA
it won't accept it. You can close the login window and the email is OK but it
does become quite annoying. What can be causing this and how can I fixe it?

Was the message a forward? did it have images or attachments? I've had the
same problem when employees of a certain large company forward me messages
with links to internal content. The link or attachment point to their
mailbox and the password dialog is asking me for their logon, not mine.
