Troubleshooting the source Exchange Server administrator's group membership

This article describes the Check group membership action of the source MAPI connection wizard. When this action is performed, the program checks if the administrator (provided in the previous step of the wizard) is a member of the Organization Management group.

If the program fails to confirm your group's membership (Fig. 1.), study the examples below that show the most common group membership issues.
