Microsoft 365 groups are a powerful feature within the Microsoft ecosystem facilitating collaboration and communication among team members. Managing these groups efficiently is crucial, and PowerShell provides robust tools to do so. One such tool is the New-MgGroupOwner cmdlet which allows administrators to add owners to Microsoft 365 groups. This article explores the syntax, usage examples, tips, use cases, possible errors, and solutions for the New-MgGroupOwner cmdlet.
Before using the Update-MgApplication cmdlet, ensure the following prerequisites are met:
Install-Module Microsoft.Graph -Scope CurrentUser
Connect-MgGraph -Scopes "Group.ReadWrite.All"
New-MgGroupOwner -GroupId <String> -DirectoryObjectId <String> [-WhatIf] [-Confirm] [<CommonParameters>]
Parameters:
-GroupId:
The unique identifier of the group.-DirectoryObjectId:
The unique identifier of the user to be added as an owner.-WhatIf:
Shows what would happen if the cmdlet runs. The cmdlet is not run.-Confirm:
Prompts for confirmation before running the cmdlet.<CommonParameters>:
These parameters include -Verbose
, -Debug
, -ErrorAction
, -ErrorVariable
, -OutBuffer
, and -OutVariable
.$groupId = "12345abc-678d-90ef-ghij-klmnopqrstuv"
$directoryObjectId = "98765zyx-432w-vuts-rqpo-nmlkjihgfedc"
New-MgGroupOwner -GroupId $groupId -DirectoryObjectId $directoryObjectId
$groupId = "12345abc-678d-90ef-ghij-klmnopqrstuv"
$directoryObjectIds = @("98765zyx-432w-vuts-rqpo-nmlkjihgfedc", "abcdef12-3456-7890-abcd-efghijklmnop")
foreach ($directoryObjectId in $directoryObjectIds) {
New-MgGroupOwner -GroupId $groupId -DirectoryObjectId $directoryObjectId
}
$groupId = "12345abc-678d-90ef-ghij-klmnopqrstuv"
$directoryObjectId = "98765zyx-432w-vuts-rqpo-nmlkjihgfedc"
New-MgGroupOwner -GroupId $groupId -DirectoryObjectId $directoryObjectId -Confirm
If you have a CSV file with a list of group IDs and directory object IDs, you can import and use them to add multiple owners:
GroupId,DirectoryObjectId
12345abc-678d-90ef-ghij-klmnopqrstuv,98765zyx-432w-vuts-rqpo-nmlkjihgfedc
12345abc-678d-90ef-ghij-klmnopqrstuv,abcdef12-3456-7890-abcd-efghijklmnop
$csvPath = "C:\path\to\your\file.csv"
$groupOwners = Import-Csv -Path $csvPath
foreach ($owner in $groupOwners) {
New-MgGroupOwner -GroupId $owner.GroupId -DirectoryObjectId $owner.DirectoryObjectId
}
Select the Group >> Select Membership tab >> Select Owners option >> Click Add owners button.
Description: The specified group or user ID does not exist.
Solution:
Description: The user running the cmdlet does not have the necessary permissions.
Solution:
The difference between New-MgGroupOwner and New-MgGroupOwnerByRef cmdlets lies in how they identify and reference the group and user objects. New-MgGroupOwner Adds an owner to a group using the group's unique identifier and the user's unique identifier.
New-MgGroupOwner
New-MgGroupOwnerByRef
$newGroupOwner =@{
"@odata.id"= "https://graph.microsoft.com/v1.0/users/{4de19c17-6a28-4a91-86d1-f717c3c8c229}"
}
New-MgGroupOwnerByRef -GroupId '1cb7317c-9c49-4dc8-a358-67ad8e95217c' -BodyParameter $newGroupOwner
The New-MgGroupOwner cmdlet is a powerful tool for managing group ownership in Microsoft 365. By understanding its syntax, usage, and potential pitfalls, administrators can efficiently delegate group management tasks, thereby enhancing team collaboration and operational efficiency. Utilize this cmdlet as part of your PowerShell toolkit to streamline group management processes and ensure that the right people have the appropriate permissions.
