Ubuntu – What’s the ‘envelope’ icon in the top panel and do I need it

messaging-menu

After a default Ubuntu 12.04 install on a new system, there always seems to be some 'Envelope' icon on the menu bar at the top. If I click it, a menu appears with Available, Away, Busy, Offline etc.

What is it, and do I need it? Or can I get rid of it, and how? I rather not have anything make unnecessary connections or poll my online status or whatever.

The messaging menu in Ubuntu provides quick access to global messaging status and individual messaging applications.

It helps you messaging or chatting a network user , or set up global account like Facebook and you can receive and send message from Facebook via it .

If you don't need it you can remove it :

sudo apt-get remove indicator-messages
