How do I set Microsoft Teams General Channel Permissions through PowerShell

Question

I am disabling permissions for everyone to chat on "General" Teams channel manually by

1. clicking on (...)
2. Manage channel
3. selecting 'Only owners can post messages'

How can I do the same with PowerShell without any manual clicks?.

Answer 1

The CsTeamsMessagingPolicy cmdlets enable administrators to control if a user is enabled to exchange messages.

Set-CsTeamsMessagingPolicy
   [-AllowUserChat <Boolean>] 

-AllowUserChat

Determines whether a user is allowed to chat. Set this to TRUE to allow a user to chat across private chat, group chat and in meetings. Set this to FALSE to prohibit all chat.

For example:

Set-CsTeamsMessagingPolicy -Identity StudentMessagingPolicy
-AllowUserChat $false -AllowMemes $false

In this example two different property values are configured: AllowUserChat is set to false and AllowMemes is set to False. All other policy properties will be left as previously assigned.
