How to  turn messaging on or off your facebook Page

You'll need to be an admin to turn messaging on or off for your Page. If you're an admin:


 Click Settings at the top of your Page.

From General, click Messages.

1. Click to check or uncheck the box next to Allow people to contact my Page privately by showing the Message button.
2. Click Save Changes.

When messaging is on, a moderator, editor or admin can send a private message from the Page to anyone who's sent the Page a message. Private messages can also be used to respond to comments on a Page's post. Keep in mind that Pages can't send messages to other Pages or to people who have blocked the Page.
