In Outlook 2007 When a user has two calendars say Test and actual calendar and he goes to View All appointment in test calendar, copy say around 20 to 30 appointments and paste them in actual calendar's "All Appointment items view, how to get a message box saying so many items copied.
And to add further to my comment above if the copy/paste is again repeated for another 50 appointment items then message box should show 50 (this count should come correctly without the need to close outlook or terminate the session
