I use this command:

Set-SPOSiteGroup -Site htt.....com -Identity newgroup -Owner newgroup2

(newgroup is a Sharepoint group, newgroup2 is another sharepoint group)

Powershell responds with this: Set-SPOSiteGroup: The user newgroup2 was not found.

What is wrong with my command? I am sure newgroup2 exists, and i am able to make it the owner of newgroup using the sharepoint interface.


You can try with the following powershell code to set the group owner,

Add-PSSnapin Microsoft.Sharepoint.Powershell

#Get the SPWeb
$web = Get-SPWeb http://url_to_web

#Get the Group
$group1 = $web.SiteGroups["newgroup"]

#Get the Group 
$group2 = $web.SiteGroups["newgroup2"]

#Assign Group as the owner
$group1.Owner = $group2

#Update the Group

Remove-PsSnapin Microsoft.SharePoint.PowerShell

Hope this helps you.


It's not possible to set an AD-group as an owner, but you can set a SharePoint group as owner as a workaround.


  1. Create a new SharePoint group, add the Security group as a member.
  2. Set the newly created SharePoint group as the owner of your existing SharePoint group

Reference: Set group owner using powershell
