Hi all,

I am looking for some assistance regarding PowerShell script.

I have managed to create Teams “Class-Test-2021” however; I would now like to add an existing Microsoft 365 group “Test-01” to the team as a member. How can I do this using PowerShell?

Thank you in advance

    Open PowerShell as administrator and follow the steps

    Type Install-Module MicrosoftTeams (if you don't have the cmdlets installed)

    Type Connect-MicrosoftTeams and log in

    Type Get-UnifiedGroup -Identity <Group> | fl ExternalDirectoryObjectId

    Type New-Team -Group <ExternalDirectoryObjectId of Group>

    You cannot nest Groups/Teams, that's not supported. In fact, when you try to do it via the UI, the current membership of the group will be expanded and added to the Team, this is what Microsoft supports.
    Afaik Microsoft is working on support for this scenario, so check the Roadmap.

    @H Mohamed ,

    I tried lots of research but find no direct command to realize this. So, it needs some more scripts to accomplish it. As script is not in our service scope, I will just provide a simple train of thought. Thanks for your understanding.

    Firstly, you could get the members’ email address of “Test-01” group by Get-UnifiedGroupLinks command: 

    Get-UnifiedGroupLinks -Identity <Test-01 GroupId> -LinkType Members

    Then, use Add-TeamUser command to add all the members to “Class-Test-2021” group. Here we need a loop statement, such as Foreach: 

    Add-TeamUser GroupId <Class-Test-2021 group Id> -User <member’s email address>
