Hello,
Our DG's have been working fine after initial setup about a year ago. Now facing problems when changing memberships of a DG. Removed members still existed and added members not.
Recreated a problematic DG. Testing...Testing... Now DG contains only Contacts-members. If I add there a User. It will not exist as a member of a DG. If DG is viewed through Management - Security Groups a User is listed as a member ok.
