When you receive an email message that has information about a meeting or a training session, you can easily add it to your Outlook Calendar by simply dragging & dropping it. From the view of the folder where the message is (most likely your Inbox), click on the little envelope icon, and drag it to the Calendar icon.

And find out how to change it from a 7-day week view to a 5-day work-week view. You can also show more or less detail in your calendar. These and more custom settings are demonstrated in this 4½ minute video http://office.microsoft.com/en-us/outlook/HA102392311033.aspx.
