# Five9 - Zendesk Sending and Receiving Internal Instant Messages

To exchange messages in real time with supervisors and other internal users, you may start or participate in chat sessions. You cannot use a chat session to communicate outside your organization. You may participate in multiple messages simultaneously. In this case, you can open each one in a separate new window. Old messages are deleted after 30 days.

In the home window, click the **Messages** tile.
