We have a BES and Domino 6.52 environment. We have a large number of users which are split into 2 departments. Each department wants to see their own address book. Howeverr when a user does a lookup from a blaqckbe rry device it looks like the BES server queries the NAB with the server ID so we can't tell who is asking the question. Is there a way of showing a customised iew of the NAB based on who is doing the lookup so users can have a customised address lookup.
