Though suggestions 1,2 and 3 are workable,
buy WMID, it is highly recommendable and behaves exactly like Identities
under OLE.
I use it to separate my business, private, clubs, nostalgia etc.
'targetgroups'.
Still using and sharing one and the same addressbook.
Used it one year now; absolutely reliable and idiotproof.
One Winmail snag: when addressbook reaches say 1000 records, opening a new
message becomes sluggish (known problem)
