On Enterprise Grid, Workspace Owners and Admins can limit who adds Matter to a new Slack or Microsoft Teams channel: in the web app open Settings, General, Channel Creation Permissions and choose All Members, Admins Only, or No Members. This prevents unwanted new channels that can affect billing.
Who can use this: Workspace Owners and Admins on the Enterprise plan. Works the same for Slack and Microsoft Teams workspaces.
For everything on this topic, see the Workspace admin collection.
By default, everyone can create new Matter channels, but you can change this to Admins Only or No Members.
Note: This setting is only available for Matter Enterprise Grid workspaces.
Edit Channel Creation Permissions
Open the Web App.
Go to Settings, then the General section.
Scroll down to the section Channel Creation Permissions.
Select the appropriate permission type:
All Members
Admins Only
No Members
Click the Save button to confirm changes.
