restrict access to executive chat

[Alexander Melara]

My company requires disabling access, so that ordinary users cannot communicate with board of directors users.

Is it possible to make this configuration?

Hi,

You could block the ports used by the chat application on a firewall or using an ACL on the specific L3 device.

You should investigate the ports used by the Chat app to avoid any impact over other services.

Using WSA:
