If you have recently ran across an issue where users are unable to manage a distribution group in Outlook or Exchange even though you have made them owners of this group it is by design.  By default users in Exchange 2013 are assigned to the "Default Role Assignment Policy".  This role does not have the permissions to edit group ownership even if they are owner's of the distribution group.  In order to fix this you must login to the ECP by going to https://servername/ecp  Once here go into the permissions on the left hand side.\ndistribution groups i own\nClick on admin roles in my instance I just assigned my user Recipient Management rights since they are an administrator level employee.  This resolves the issue.\npermissions\nIf all of the following hold true then you can also just download and run this Powershell script.\n
