When you block users from joining external meetings, they can't join meetings that are hosted from Webex sites outside of your organization. But you can allow users to join meetings on certain Webex sites, by adding those Webex sites to an approved list setting.


Sign in to Control Hub, and go to Services > Meeting.


Click Settings.


Under Meetings, select one of the following next to External:

  • Allow all external sites—Users are allowed to join all external meetings.
  • Allow approved external sites—Users can only join external meetings from approved Webex sites.
  • Block all external sites—Users aren't allowed to join external meetings from any Webex site.

If you selected Allow approved external sites, enter a Webex sitename and click Add.

What to do next

If you allow users to join external meetings, you can select which collaboration features users have available to them during external meetings.
