how to remove unlicensed people from group chat by powershell?

[StanleyHao]

hi gents,

i have a request to bulk remove unlicensed people from chat group, which is self-organized by random users

since unlicensed people are in many chat groups, manual way costs too much time, so i am wondering if there is a programming way to do the job

thanks for your ideas

Hi @StanleyHao

Sorry, nothing in the PowerShell cmdlets which point to being able to do this programmatically.

https://docs.microsoft.com/en-us/powershell/teams/intro?view=teams-ps

I would recommend raising it on uservoice (https://microsoftteams.uservoice.com/forums/555103-public) whilst it is still around in order to raise it as a new feature. As far as I know this is the only possible way is

Note - If someone leaves or is removed from a group chat, their messages will remain in the group chat history

Hope that answers your question

Best, Chris

I'll go to uservoice to raise the request.

It is possible via MS Graph so if someone will find this thread, this may be still helpful:

#Install-Module -Name Microsoft.Graph (big module!)
Connect-MgGraph -Scopes Chat.ReadBasic,ChatMember.ReadWrite
$mbrs = $null
Get-MgChat -All|where chattype -eq 'group'|%{
	$chatgrps = $_
	$mbr = Get-MgChatMember -ChatId $_.Id
	$mbrs += ,$(''|select @{n='Topic';e={$chatgrps.Topic}},Roles,@{n='ChatType';e={$chatgrps.ChatType}},@{n='CreatedDateTime';e={$chatgrps.CreatedDateTime}},@{n='LastUpdatedDateTime';e={$chatgrps.LastUpdatedDateTime}},@{n='ChatId';e={$chatgrps.Id}},@{n='MembersId';e={$mbr.Id}},@{n='Members';e={$mbr.displayname}})
}
$mbrs|where members -Contains '{Name of the user for removal}'|fl *

This will list all groups where user is joined and its ChatId and MemberId.
Below code (with correct ChatId and MemberId) will remove user from group.

Remove-MgChatMember -ChatId '19:adfgdfgfdff09f9f8cdhdghhfdff4607f@thread.v2' -ConversationMemberId 'MCMfghgfhfghfghJhOGItYgfhfghgf2YfffffZjM2NzIyZjNhIyMxOTphNGQ1NWJlNzAxhgfhfghfg2RmMmJlYWY0NjA3ZkB0aHJlYWQgfhgfhgfNi1iNTRmLTE5fghgfgZTA0MWYyZA=='
