question

@NMBabu-1149 ,
If I understand correctly you would like to create a script which adds multiple owners to multiple groups by running a single powershell script . This can be done in multiple ways however I would use the simplest one. You would need to create a csv file with all the details for the owners that you want to add.

• Export the list of groups in your organization with Object Ids and Display names. The output should look like in the screenshot.

   Connect-AzureAD       
   Get-AzureADGroup | Select-Object ObjectID, DisplayName | Export-Csv c:\temp\group.csv

• Export a list of users in your organization which you would like to add as owners with their Object Ids and Display Names . The output should be as in the screenshot.

  
  

       Connect-AzureAD       
       Get-AzureADUser | Select-Object ObjectId, DisplayName | Export-Csv C:\temp\users.csv

• Create a new csv file with the list of groups and the list of users to be added as owners. This is a manual step and will take time.
  

• If you require to set multiple owners of the same group , you need to add the same group in the line.
  

• Also if you see the details , I have modified the column titles to gObjectId (group objectid) gDisplayName (group displayname) UserOId (user objectid) UserDisplayName (user name) as per the usage in the script .
  

  • 

      Connect-AzureAD
            $Groups = Import-Csv "C:\Temp\groupOwner.csv"| ForEach-Object { 
                 Add-AzureADGroupOwner -ObjectId $($_.gObjectId) -RefObjectId $($_.userOid)
                 Write-Host "$($_.UserDisplayName) was added as a owner of the group $($_.gDisplayName)"
                 Get-AzureADGroupOwner -ObjectId $($_.gObjectId)
                 }
    

    
    

The output is received as below for the above script .

Hope the above fits your requirement . Should you have any further query , do let us know. There could surely be other ways to do the same thing . But this will work for bulk group to bulk owner assignment . In any case you would have build a csv file beforehand in order to do it onetime.
