Exchange 2007 User receives appointment confirmation for another user

OllarConsulting used Ask the Experts™
I have a Small Business Server 2008 running Exchange 2007.  One particular user, who is a member of the Administrators group, receives ALL appointment confirmations for another user regardless of whether he has been included in the invite or not.

For example, User B will send an appointment invite to User C ( user C can be internal or external - it doesn't matter ).  When User C accepts the request from User B, User A receives the confirmation.

User A does not have Full Access Permission or Send As Permission on the User B's mailbox ( nor does Administrator ).

I have looked everywhere and am stumped.
