You receive an error message when you modify a distribution list in Outlook

If you try to modify a distribution list in Microsoft Outlook, you may receive the following error message: You may receive this error message even though you are using an account that has sufficient permissions, such as a domain Administrator account or an enterprise Administrator account.

This behavior may occur if the Outlook client is accessing a global catalog in a domain where the distribution groups do not exist.

This global catalog does not contain a writable replication of that Universal Security Group (USG) or Universal Distribution Group (UDG), and you cannot make changes to it.

To resolve this behavior, move the Universal Security Group or Universal Distribution Group to the same domain where the global catalog and mail-enabled users are located.

As an alternative, you can make the Outlook client use a global catalog server that is in the same domain as the distribution group. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
