Hi, I want to add an exising user to a team chat with PowerShell, but I can't find a working solution in the documentation or on google, hopefulle someone can help here: I found following commands, but non of them I get to work: New-MgUserChatMember --> Throws error when using Add-MgUserChatMember --> Throws error when using Add-MgChatMember --> I don't know how to build BODYPARAMETERS To my script: first I installed all modules of Microsoft-Graph: Install-Module Microsoft.Graph Find-Module Microsoft.Graph.* | Install-Module Then I connected to MS-Graph: Connect-MgGraph Here I get the user which should be added to the chat(s): $user = Get-MgUser -Filter "UserPrincipalName eq 'email address removed for privacy reasons'" Now get the chat groups where to add the user, and add it with the commands above $groups = Get-MgChat -Filter "ChatType eq 'group'" | Where-Object Topic -in $chatgroups foreach ($group in $groups) { New-MgUserChatMember -UserId $user.Id -ChatId $group.Id Add-MgUserChatMember -UserId $user.Id -ChatId $group.Id } But when I run this I get following error messages: New-MgUserChatMember : Requested API is not supported. Please check the path. At N:\Administration\IT\60 Tools\PowerShell\MS-Teams\SyncMSTeamsChatGroupMembers.ps1:93 char:25 + ...

Is there a special authentication needed. How to implement this? I would appreciate any help, thanks in advance. Rainer
