Calendar missing in OUTLOOK 2010

Opened my outlook today morning and Calendar icon was missing.

There are two ways we could get it back.

1. Press keys CTRL+6 and it lists all the bells and whistles under your account in outlook.

2. In outlook go to bottom left part of page and right click any available option.

 Right click on any of the available icons and select option "NAVIGATION PANE OPTIONS.."

This will open up the following prompt. Select option calendar and click OK.

Hope this helps.....
