I share contacts, tasks and calendars with my business partner. I have the
contact data base loaded under me. When I open her tasks to create a new task
for her, because I do not want to have to send her an email every time, I
link it to the contact under "my contacts". However, when I click on that
contact's name and activity, it doesn't show the task that I just created
under my business partner (Mary's) tasks.

How do I get them to show under my contacts? Or how do I assign a task to
Mary without sending her an email.

Thanks.
