Question

Hi All

I am executing the below syntaxes to create DL and mail enabled security group, i am getting the below error. if i remove -OnPremisesOrganizationalUnit the syntax works fine. i want to create this in a particular OU. Experts guide me.

New-DistributionGroup -Name "DL1" -Alias "DL1" -DisplayName "DL1" -SamAccountName "DL1" -OnPremisesOrganizationalUnit "OU=MyOU,DC=contoso,DC=com"

New-DistributionGroup -Type Security -Name "MG1" -Alias "MG1" -DisplayName "MG1" -SamAccountName "MG1" -OnPremisesOrganizationalUnit "OU=MyOU,DC=contoso,DC=com"

Use
-OrganizationalUnit

New-DistributionGroup -Name "DL1" -Alias "DL1" -DisplayName "DL1" -SamAccountName "DL1" -OrganizationalUnit "OU=MyOU,DC=contoso,DC=com"  

"OnPremisesOrganizationalUnit" only applies for remote mailboxes:
