Mail Enabled Groups Empty in outlook

[Jonas Haggren]

Some of our Groups are empty of members in outlook. But then we look at the
groups in Active Directory Users And Computers the members are there.

The manager of the group who have the right to update the members of the
group, Are not allowed to do this from outlook.

These groups are not possible to e-mail to from Outlook And we get this
error..
A configuration error in the recipient's e-mail system prevented delivery of
this message. Two recipients are configured with the same e-mail address.
Contact your administrator.

Then i got this error and then use the Send Again button and send the e-mail
again. It works perfectly fine to send the e-mail, It works also to send the
e-mail if i use the e-mail address of the e-mail enabled group. But it
doesn't work then i pick the group from the Global Address List

Outlook only knows how to query GCs for group membership, this means that the
DLs MUST be Universal in order to always see the membership. On top of that, it
is possible to set the membership of a group to be hidden though if you do that,
you won't be able to see the membership from ADUC as well (assuming it is the
same user using both methods).

If you have a multidomain forest you almost certainly do not want to use Outlook
to manage DL membership due to issues resulting from which GCs you connect to.
