I was able to move all my mail and contacts to a new folder but how can I do the same for my calendar appointments and meetings?
The day/week/month view of the Calendar folder indeed makes it impossible to move all your calendar items at once. By switching your Calendar view to a list view, you can move your calendar items in the same way as that you did for your emails.
- Outlook 2002/XP and previous
View-> Current View-> By Category
- Outlook 2003
View-> Arrange By-> Current View-> By Category
- Outlook 2007
View-> Current View-> All Appointments
- Outlook 2010 and Outlook 2013
View-> Change View-> List
Changing your Calendar view to a list view makes moving your items much easier.
