Problem: The "Mail" button is missing

You can customize the toolbar to add or remove icons, including the mail icon

1. Right-click the Star icon in the IE window
2. Choose Customize Command Bar
3. Choose Add or Remove commands
4. Click on the Read Mail item in the Available toolbar buttons list
5. Click the Add button to move the button to the Current toolbar buttons list
6. Click the Close button

If the button still isn't visible, it may be pushed off the side of the screen. To fix this:

1. Right-click the Star icon in the IE window
2. Uncheck Lock the Toolbars
3. Drag the dotted splitter in the command bar to the left until all of the buttons are visible
