Bulk add/remove users to Microsoft Teams using the CLI for Microsoft 365

We will continue our journey with the most popular sample scripts created  for the CLI for Microsoft 365. This time we will show you how to add and remove users to Microsoft Teams in bulk. The original script was created by our community member Joseph Velliah.

The script requires a CSV file with different parameters:

• groupMailNickname: the mail alias used for the Microsoft 365 Group associated to the current team

• userPrincipalName: the UPN of the user that should be processed

• role (owner, member): the role of the user. Can be owner or member. Keep it empty if you want to remove a user

• operation (add, remove): operation to execute

groupMailNickname1, user1@domainname.com, owner, add
groupMailNickname2, user2@domainname.com, member, add
groupMailNickname3, user3@domainname.com, , remove

The script in question looks as follows:

$taskItems = import-csv "sample-input-file.csv" –header mailNickname, userEmail, role, action
$groups = m365 aad o365group list -o json | ConvertFrom-Json

ForEach ($taskItem in $taskItems) {

    $mailNickname = $($taskItem.mailNickname)
    $userEmail = $($taskItem.userEmail)
    $role = $($taskItem.role)
    $action = $($taskItem.action)

    $group = $groups | Where-Object { $_.mailNickname -eq "$mailNickname" }
    $user = m365 aad user get --userName $userEmail -o json | ConvertFrom-Json

    Write-Host "Processing: User --> " $user.mail " Group --> " $group.mailNickname

    If ($action -eq "add") {

        If ($role -eq "owner") {
            m365 aad o365group user add --groupId $group.id --userName $user.mail --role Owner;
            Write-Host $user.mail " added as owner in " $group.mailNickname
        }
        ElseIf ($role -eq "member") {
            m365 aad o365group user add --groupId $group.id --userName $user.mail
            Write-Host $user.mail " added as member in " $group.mailNickname
        }
        Else {
            Write-Host "Invalid user role '" $role "'"
        }
    }
    ElseIf ($action -eq "remove") {
        m365 aad o365group user remove --groupId $group.id --userName $user.mail --confirm
        Write-Host $user.mail " removed from " $group.mailNickname
    }
    Else {
        Write-Host "Invalid task action '" $action "'"
    }
}

What is the CLI for Microsoft 365?

CLI for Microsoft 365 is a cross-platform CLI that allows you to manage various configuration settings of Microsoft 365 and SharePoint Framework projects no matter which operating system or shell you use.

While building solutions for Microsoft 365 expands beyond the Windows operating system, managing many of the platform settings is possible only through PowerShell on Windows. As more and more users work on non-Windows machines, it’s inconvenient for them to have to use a Windows virtual machine to configure their tenants. With the CLI for Microsoft 365, you can configure your tenant no matter which operating system you use. Additionally, using CLI for Microsoft 365, you can manage your SharePoint Framework projects.
