Ol2000 sr-1 Exchange 5.5 address lookup issue with old GAL entry show X400 address

[Bob [BVP]]

I am having a issue where an old GAL entry is being brought up in
OL2000 sr1 from EX55. It comes up using the first name, but if
I use the last name too, it fails the GAL lookup. This mailbox in
Exchange has been Hidden, but still comes up with Dashes under
it. All my other hidden recipients that were in the GAL do not
behave this way. There are no personal DL's, Contacts etc.. with
this name in it either.. Any clues would be appreciated.. Oh, and
if I do properties of it, it is an EX type address showing the X400
address of the mailbox ?

Thanks in Advance,
Bob
