MS Teams: Create Teams and add Members based on Group Membership

By Patrick Gruenauer on 1. June 2021 • ( 2 Comments )

So, you are about to move to the cloud and now you want to create teams for your organization based on the group membership of your users. You also want to name the teams the way the groups are named. In this blog post, I’ll show you how to do that.

Let’s get started.

Connect to Microsoft Teams

First install the PowerShell Module for MSTeams and connect to your cloud tenant.

Install-Module MicrosoftTeams # if neccessary
Connect-MicrosoftTeams

If you see the screen above, move on.

Create Teams and add Members based on Group Membership

The following code gives you an example of how to create Teams and to name them the same as your groups the users are member of. All group users retrieved are automatically added to each new team.

# Create Teams and add members based on group membership
 
$groups = Get-ADGroup -Filter * -SearchBase "OU=groups,DC=domain,DC=com" |
Select-Object -ExpandProperty Name
 
foreach ($g in $groups) {
    $users = Get-ADGroupMember -Identity $g | 
    Select-Object -ExpandProperty SamAccountName
    $team = New-Team -DisplayName $g -Visibility Public 
 
    foreach ($u in $users) {
        $name = $u + '.' + $env:userdnsdomain.ToLower()
        Add-TeamUser -GroupId $team.groupid -User $name
}
}

I ran the script. The Teams are created but not populated. The ‘get-adgroupmember’ does not produce userprincipalname only samaccountname. Am i missing something?
