Sorry, I have not used Outlook much but it was my understanding that
appointments and such could be shared, thus implying some
communication between the calendar (maybe via Outlook) and others in
a team.

This is true, but how does that imply "internet" to you? If you have a
backend for the sharing, it will occur over the local area network. See

Outlook 2007 has the ability to publish a calendar to the Internet, but it's
read-only. Recent versions can save the calendar as a web page which you
can publish to a web site of your own.
