Answer 1

Hi,

The PowerShell cmdlet ‘Get-AzureADUser’ is used to retrieve guest users in the tenant. To list all the guest accounts, run the following. 

Get-AzureADUser -All $true -Filter "UserType -eq 'Guest'"

Answer 2

List all guests in Microsoft Teams teams in the tenant and export the results in a CSV.

Install-Module MicrosoftTeams
Connect-MicrosoftTeams
$teams = @()
$externalteams = @()
$teams = get-team
foreach ($team in $teams){
  $groupid = ($team.groupid)
  $users = (Get-TeamUser -GroupId $team.groupid | Where-Object {$_.Role -eq "Guest"})
  $extcount = ($users.count)
  foreach ($extuser in $users){
    $id = $team.groupid
    $teamext = ((Get-Team | Where-Object {$_.groupid -eq "$id"}).DisplayName).ToString()
    $ext = $extuser.User
    $externalteams += [pscustomobject]@{
      ExtUser   = $ext
      GroupID   = $id
      TeamName  = $teamext
	} 
  }
}
 if ($externalteams.Count -gt 0){
    Write-Host "Exporting the guest members in teams results.."
    $externalteams | Export-Csv -Path "GuestUsersFromTeams.csv" -NoTypeInformation
    Write-Host "Completed."
 }
 else{
    Write-host "there are no external user added to any team in your organization" -ForegroundColor yellow
 }

Hi @Anonymous

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your problem is related to development, which we are not very familiar. The following suggestion is just for your reference. Thanks for your understanding!

Please run the following command. Returns an array containing the UPN, UserId, Name and Role of users belonging to a specific GroupId.

Get-TeamUser -GroupId  -Role Guest
