right click an appointment and choose create task in outlook
 

As a busy service person in a small business, I often create my 'jobs' in
outlook calender as an appointment guessing the amount of time it will take,
but it would be better as a task so I can track and progress it. So it would
be nice if I could right click a reminder or appointment and create a task
from it. I already know you can drag and drop a calender item onto the tasks
shortcut icon.
