The To-Do Bar is extremely flexible; you can customize it to your needs.

Click View, click To-Do Bar, and then click Options. From here you can turn elements of the To-Do Bar on or off, and also select how many appointments you want to see.
This is useful on busy days with multiple appointments, because you can see them all at a glance.

Instant messaging is the quick way of replying to non-essential e-mail. You can save valuable time by answering routine messages with instant messages instead of e-mail. Click Reply on the toolbar, and then select Reply with Instant Message from the drop-down menu. This will start Microsoft Office Communicator, which you can then use to send an instant message in less time than a conventional e-mail message.
