Get AzADGroupMembers from nested groups

Hi,   I'm  trying to get all members of a group (including nested groups members) to add to a teams private channel.   We have a script to add members of a group to a private channel, but it will...

Eivind_G here's a suggestion. Get-AzADGroupMember doesn't have a -recurse parameter like it's on-premises Active Directory equivalent, but you can recursively search through the groups with something like this:

function Get-AzADGroupMemberNested($ObjectId) {
	#Get the members of this group
	$members = Get-AzADGroupMember -ObjectId $ObjectID
	foreach ($member in $members)
	{
		if ($member.OdataType -eq "#microsoft.graph.group")
		{	
			#If member is a group then recursively look at group membership
			Get-AzADGroupMemberNested -ObjectId $member.ID
		} elseif  ($member.OdataType -eq "#microsoft.graph.user") {
			#If member is a user Add to Team Channel
			#Get mail of User associated with ID
		    	$User = (Get-AzADUser -objectid $member.ID).mail
			Add-TeamChannelUser -GroupId 'teams_groupID_here' -DisplayName 'Private_channel_name' -user $User
		}
	}
}

Get-AzADGroupMemberNested -ObjectId 'source_groupID_here'

ChrisBradshaw This is a modified version I use to get members on nested groups:

 

function Get-AllGroupMembers {
    param (
        [Parameter(Mandatory = $true)]
		$GroupId
    )

    # force results into array in case of one member
    $members = @(Get-AzADGroupMember -ObjectId $GroupId)

    foreach ($member in $members) {
        if ($member.OdataType -eq "#microsoft.graph.group") {
            # If the member is a subgroup, recursively get its members
            $subgroupMembers = Get-AllGroupMembers $member.Id
            $members += $subgroupMembers
        }
    }

    return $members
}

Get-AllGroupMembers $group.id
