It’s possible that there will be instances when you want to limit the number of @all messages that are sent in a certain space. If you are the moderator of the space, you have the ability to block the @all function, which will prohibit users from simultaneously naming everyone in the space.
Go to Space Information in the space, and then click the button labeled “Disable @mentions to all.”
Only on your PC can you disable it, but it will be disabled for anyone who uses the Webex App on their mobile device as well.
You can once again enable @mentions to all by going to Space Information and clicking the button labeled Enable @mentions to all.
