Using Powershell Microsoft Teams module in a GUI app will not shutdown the process when form closed

[DarusDP]

I have a GUI app written in Powershell that works correctly except when I connect to MicrosoftTeams (and even disconnect) then the GUI app process will not end. If I remove the connection to MSTeams the process ends correctly (not in task mgr process list anymore). So I'm confident I've narrowed the issue down to the MSTeams connect/disconnect.

Here is code snipet for connect/disconnect.

$script:msteamsSession = Connect-MicrosoftTeams -Credential $script:O365CredDefault

Disconnect-MicrosoftTeams -Confirm:$false

It does seem to be an issue in non-GUI scripts also.

When I run PS ISE and do MSTeams connect then close PS ISE, the process is still running. Yes I gave it time to shutdown.

Try unloading the module as well?

Unfortunately remove-module -Name MicrosoftTeams didn't work

Not ideal or elegant but

Stop-Process -Id $PID 

seems to work

Hopefully Microsoft Teams module developers will discover the real problem and fix it.
