How to add bulk users from CSV file to MS Teams using PowerShell

How to add bulk users from CSV file to MS Teams using PowerShell

Hi everyone !! Today we will see How to add bulk users from CSV file to MS Teams using PowerShell. We will use PowerShell script to add the users. I know there must be other ways also to do this but as I am big fan of PowerShell scripting. Hence I have done it using scripting.

Connecting MS teams via PowerShell

  1. Install Microsoft teams module for MS Teams.
  2. Launch powershell with admin rights.
  3. Run Install-Module -Name MicrosoftTeams
  4. Refer this link for package information
  5. Type “A” to install all the features.

In my previous blog I have described How to install and connect with Power Platform ? This also a bit similar to this, you can refer earlier blog for an idea.

Connect to MS Teams

Run command “Connect-MicrosoftTeams” and enter the credentials.

Once you provide the credentials, you will able to see below screen.

Prepare your CSV file

After connecting to MS team, now we will prepare our csv file. Refer below screen shot to make a csv file. Save the csv file as Adduser. You can save this file whatever name you like.

PowerShell Script to create Team and User.

Add Users in Teams

##This script will be used to create a Team and add bulk user from csv file to the newly created team.
##Before running this script use Connect-MicrosoftTeams to connect your MS Teams.
##Version 1.0 Date 24-2-2020
##Created By Rakesh Pandey
$date = Get-Date -Format M
$logfile = "E:\Powershell_Output_Script\$date-useraddlog.txt"
$startdt = [System.DateTime]::Now
Write-Output "Start Time: $startdt rn" | Out-File $logfile -Append
Write-Output "**" | Out-File $logfile -Append
$inputcsvfile = Import-Csv (Read-Host "Enter CSV Location")
$teamName = Read-Host "Please enter Team Name"
$teamDescription = Read-Host "Please enter Team Description"
##Create Team
New-Team -DisplayName $teamName -Description $teamDescription
$grp = Get-Team -DisplayName $teamName
$grpid = $grp.GroupId
Write-Output "Created Team: $teamName groupid: " $grpid | Out-File $logfile -Append
##Add user from csv file
foreach($line in $inputcsvfile)
Add-TeamUser -GroupId $grpid -User $line.EmailAddres -Role $line.Role -ErrorAction SilentlyContinue
Write-Output "Added user: "$line.EmailAddres" Role: "$line.Role | Out-File $logfile -Append
Write-Output "**" | Out-File $logfile -Append
$enddt = [System.DateTime]::Now
Write-Output "End Time: $enddt rn" | Out-File $logfile -Append

This script requires below information from user.
1) CSV file name and location
2) Team Name
3) Team Description
After providing these details you will able to see the new team under teams and user already added into it.

  1. Thanks for the Tutorial!
    This would be even better if there is a way to define the SMTP email address when the Teams is created. Because as currently, a randomly generated email is assigned to the group.

    Hi John,
    Thanks for visiting our site and suggestion. We can provide a user friendly Mail Nick name using -MailNickName parameter.
    The MailNickName parameter specifies the alias for the associated Office 365 Group. This value will be used for the mail enabled object and will be used as PrimarySmtpAddress for this Office 365 Group. The value of the MailNickName parameter has to be unique across your tenant.
    So the updated code will be like below.
    ##Create Team
    New-Team -DisplayName $teamName -Description $teamDescription -MailNickname “userfriendlynamewithoutspace” .
    Please try at your end and let us know whether its working or not.

      Hi Vinny,
      You can use Add-TeamChannelUser -GroupId 31f1ff6c-d48c-4f8a-b2e1-abca7fd399df -DisplayName “Engineering” -User -Role Owner command. You can use the csv file the way I have used. If unable to form the script, please let me know.

    Hi Rakesh

    Great tutorial, any pointers on how it could be modified, to create the teams from a CSV and populate each teams membership

      Hi Justin,
      Thanks for glancing the tutorial. In order to create a new team you can use New-Team command. See the below example from MS site. You can incorporate this in a CSV file. Follow this link for more details :
      $group = New-Team -MailNickname “TestTeam” -displayname “Test Teams” -Visibility “private”
      Add-TeamUser -GroupId $group.GroupId -User “”
      Add-TeamUser -GroupId $group.GroupId -User “”
      Add-TeamUser -GroupId $group.GroupId -User “”
      New-TeamChannel -GroupId $group.GroupId -DisplayName “Q4 planning”
      New-TeamChannel -GroupId $group.GroupId -DisplayName “Exec status”
      New-TeamChannel -GroupId $group.GroupId -DisplayName “Contracts”

      Also let us know if you need any helping hand to build the script.

      Hi Sam,
      Currently, Microsoft Teams cmdlet doesn’t provide any command to add guest users.
