If the user is in Domain A (same as the distribution list) I can add them to the exchange recipient adm group and they can use Outlook 2007 – start a new message – right click on a distribution list – select properties – modify members. This works.

However, if the user is in domain B this will not work. They get a “do not have sufficient permissions” error message. (Global Catalog read-only for objects). I have tried changing the distribution list security to give them full control. Added the user as “managed by – manager can update list”. Added the user to the exchange Organization Adm group and they cannot modify the members of the distribution list as noted above. If I add active directory users and computers to a console for them they can modify members but I would rather not have them accessing users and computers.

It looks like AutoDL was used for a way around this up to Exchange 2003. Has anyone tried this with 2007?

Has anyone delegated across domains to allow users to modify members? Possibly via a third party tool?

Thank you,
