Custom actions are not available in the Essentials solution.
Use the scripts below to retrieve a list of all guests and external users in a specific Teams group.
In PowerShell:
param ([string]$Id)
$TeamsGuests = @{}
$OrgName = “@” + (Get-OrganizationConfig).Identity
$Team = (Get-UnifiedGroup -Identity $Id) #Populate the array with current group membership
Get-UnifiedGroupLinks -LinkType Member -Identity $Team.Alias | % { $User = $_.Name.tostring() #Handle guest users
if ($User -like "*#EXT#*") {
$GuestUPN = $User + $OrgName
$GuestUser = Get-AzureADUser -ObjectId $GuestUPN -ErrorAction SilentlyContinue #Handle specific case for user displaynames containing commas
$GuestDisplayName = $GuestUser.DisplayName -replace ",", ""
$TeamsGuests.Add($GuestDisplayName, $GuestUser.Mail)
}
}
$TeamsGuestsjson = ($TeamsGuests | ConvertTo-Json)
$TeamsGuestsjsonClean = $TeamsGuestsjson -replace ",", "<br>"
$TeamsGuestsjsonOut = $TeamsGuestsjsonClean.Trim([char]0x007B, [char]0x007D)
return $TeamsGuestsjsonOutIn a CoreView custom action:
