Outlook 2007: Delete Old Appointments to Reduce the Size of Your Mailbox
Contributed by Rob Rogers 
Tagged: Microsoft Outlook Appointments (particularly those with attachments) can slowly add up over time. If you work for an organization that limits mailbox size, available space is always a critical item. Instead of having to search through your calendar month by month, you can simply pull up a list of all appointments and then choose those that you no longer need and delete them.
1. Open the Outlook Calendar.
2. Click View.
3. Mouseover Current View, and select All Appointments.
4. Select and delete the desired appointments.
5. Go to your Deleted Items and permanently delete the items from your mailbox.
