Actually on the MAPI level, PR_EMS_AB_IS_MEMBER_OF_DL property can be
retrieved as IMAPITable. It will list all the DLs that the giveb user is a
member of.

Redemption exposes PR_EMS_AB_IS_MEMBER_OF_DL as
theRDOAddressEntry.IsMemberOfDL property -

set Session = CreateObject("Redemption.RDOSession")
Session.MAPIOBJECT = Application.Session.MAPIOBJECT
set AddressEntry = Session.AddressBook.GAL.ResolveName("dmitry")
Debug.Print "-- Delegates (who can send of behalf of " & AddressEntry.Name
& ")"
for each AE in AddressEntry.Delegates
Debug.Print AE.Name
next
Debug.Print "-- Is delegate for (can send on behalf of these users)"
for each AE in AddressEntry.IsDelegateFor
Debug.Print AE.Name
next
Debug.Print "-- Is member of the following Dist Lists:"
for each AE in AddressEntry.IsMemberOfDL
Debug.Print AE.Name
next
Debug.Print "-- The following users report to " & AddressEntry.Name
for each AE in AddressEntry.Reports
Debug.Print AE.Name

VBA is irrelevant, it would be the same with VB6, VB.NET, C# or any other
language. The limitations are what's available in the Outlook object
model. Even other lower level API's wouldn't let you query which DL's a
person belongs to, perhaps an LDAP query might do that. That I'm not sure
of, I rarely use LDAP.

Thanks Ken,

it really helps me, I can read the members of a DL but the other way
would
be esaier for me, I mean, to obtain the DLs a sernder of a mail is
member
of through the GAL. I'm afraid this way is not possible with only de VBA
object model.
