Hello,

You can modify distribution groups owner, if you own the group like this :

Get-DistributionGroup -Identity MyDL | Set-DistributionGroup -ManagedBy admin@itfordummies.net

But, if you aren’t a current owner, but an Exchange admin, this will fail. You need to use an additional switch :

Get-DistributionGroup -Identity MyDL | Set-DistributionGroup -ManagedBy admin@itfordummies.net -BypassSecurityGroupManagerCheck
