Dear all, I'm a novice about outlook programmmer. Now,there is a problem when I write the code for atuomatic sending the email. according the article from the microsoft: http://support.microsoft.com/kb/239087/en-us/ I created the task, but when I receive the reminder that the task is due, It can't send the mail automatic, I should give the "Complete" flag to trigger the Item_PropetyChange() event.But I want it complete automatic sending the mail. How can I do? I think I should add a another event about the task overdue, but I don't know how to do? pls help! Thanks! Sam
