I try to grant a user the SendOnBehalf-Permission for a Distribution Group in Exchange 2010
I use the following command in the EX2010-Shell
Set-DistributionGroup -Identity "DLName" -GrantSendOnBehalfTo USERNAME
but I receive the following error-message:
Not enough permissions. This task can only be performed by a manager of this group. OperationRequiresGroupManagerPermissions.
The user account I use to start the Ex2010-Shell has Domain- and Enterprise-Admin-Rights. How can I not have enough permissions ?
