This is a gotcha when dealing with the "Managed By" attribute of mail-enabled security and distribution groups. I found in my environment running Exchange 2013 SP1 that I am unable to change group membership by either using Exchange Management Shell (EMS) or Exchange Control Panel (ECP). The account I was using was both a Domain Admin and a member of the Organization Management security group.
I attempted to add myself to a group called "Avantgarde Users" to the ManagedBy attribute using Exchange Control Panel however received the following error message:
You don't have sufficient permissions. This operation can only be performed by a manager of the group.
Using the Exchange Management Shell the same problem was experienced.
Using the exact same administrative account, I was able to perform this task using Active Directory Users and Computers.
Once I added myself through Active Directory users and computers, my account appeared under ownership in Exchange 2013 Exchange Control Panel as normal.
EDIT: If you use the -BypassSecurityGroupManagerCheck switch on the PowerShell command it will work. In my opinion it seem silly to check if your a manager of the group especially if a group has no managers.

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
