# Replacing a Messaging Server

You can replace a messaging server with another server.

**Note**

When three servers are specified as messaging servers, you cannot add another server, but only replace an existing messaging server.

**To replace a messaging server:**

1. In the global administration view, select **Services > Messaging** in the navigation pane.  

The **Messaging** page is displayed.
