We are using Exchange 2010 as part of an Office 365 subscription. We have a security group owned by Alice only. Without using Alice's account, how can the administrator take ownership of that security group?
PS C:\> Get-DistributionGroup "SecurityGroupX" | Select ManagedBy -ExpandProperty "ManagedBy" namprd00.prod.outlook.com/Microsoft Exchange Hosted Organizations /example.onmicrosoft.com/alice
I am a member of the Organization Management role, so I expected to be able to override this permission. I tried using the Exchange management portal, and I also tried using PowerShell:
PS C:\> Set-DistributionGroup "SecurityGroupX" -ManagedBy "firstname.lastname@example.org" You don't have sufficient permissions. This operation can only be performed by a manager of the group. + CategoryInfo : NotSpecified: (:) [Set-DistributionGroup], OperationRequiresGroupManagerException + FullyQualifiedErrorId : 99CEE042,Microsoft.Exchange.Management.RecipientTasks.SetDistributionGroup + PSComputerName : bl0prd0000psh.outlook.com
