I have an interesting problem going on and would like feedback from anyone
who can help.

We are running Outlook 2003 with an Exchange 2003 Enterprise server. I had
a former employee Mary Jo who was given right to view the calendar of her
boss and assist him with his scheduling. She left the company and a new
employee took her place. Her domain account and email account were deleted
from the server. Here is where it gets interesting. Now whenever a user
in Outlook submits a new meeting request to her boss by selecting the boss's
email from the global address list (I don't think it matters how you enter
the boss's email) from within their exchange calendar, they get a email
message back stating an email to Mary Jo was undeliverable. Here boss also
gets the meeting request email and that part works okay. But why is there
an email also sent to Mary Jo?

I have check everywhere trying to find a rule that would forward an email to
Mary Jo if a meeting request was made to her boss, but have not found one.
Does any one know what is going on here and how to stop Mary Jo from getting
sent a email in this case.
