I go into EMC to add new members to a Universal Distribution Group and when I apply the changes I tells me that the previous members are already members and will not apply my changes. I believe that I have been able to do this before I upgraded to Rollup 2 but not sure. Anyone else experiencing this issue? I realize that I can go into AD Users and Computers and add it there without error but I am sure I've been able to do this before.
