Creating group in Web Interface default of not creating Exchange email address includes mailNickname and edsaAdminGroup in request.
Creating a new group in the Web Interface, the default unchecked value for creating an Exchange email address does not gray out the mailNickname or edsaAdminGroup attributes so they are still included in the request. This causes the groups to be created with a broken Exchange state. The policy should be disabling both attributes by default since it's not checked off.
