I often schedule teleconferences and need to provide attendees with a call in
number and a participant passcode.

In addition, I also need to include the Chairperson Passcode in my meeting
notice and make the note Personal to prevent anyone else from seeing my
code.

I like having the codes readily available in my calendar so that I can use
my PDA in and out of the office to quickly start meetings.

I am somewhat surprised that this functionality isn't already incorporated
into Outlook.
