We have a new computer that has Microsoft 7 as well as functions of 8.  The computer is an HP 500. I need to set up an interactive calendar that I will maintain but has appointment spaces for several employees and has the option to invite office personnel to make additions or send me emails to make changes.  It has been several years since I have used Outlook so I am not real familiar with the new Outlook.  Is there a tutorial that I can use to educate myself on its operation?
