Untrue - nested Distribution Lists can be stored in the Contact's folder for the user. Where did you hear otherwise? However, like Sue, I find categories far more flexible.

||| Hello,
||
||| We're migrating to Exchange/Outlook 2003 from a mail system which
||| allows nested distribution groups in the users' Contacts folder. The
||| migration tool can't migrate any nested groups because Outlook
||| doesn't support them.
||
||| Can anyone suggest a workaround please?
||
||| AD does allow nested distribution groups but company policy doesn't
||| allow external contacts in the AD. Plus the groups are in a few
||| hundred departmental mailboxes - not personal ones - so we don't
||| want to shift management of the lists (creation, updating,
||| assignment of permissions) from the users to the administrators.
||
||| It's a showstopper for us.
||
||| Thanks,
||
