How to Delete All Calendar Entries in Outlook
If you have set a certain schedule for yourself using the calendar in Outlook and then find that your schedule will be much different than what you have entered on the calendar, you may want to get a fresh start and delete all of the calendar entries. This is common in cases in which a person gets a promotion or changes vacation dates. Instead of simply creating a new calendar and ignoring the old one, Outlook users have the option of clearing out the information from their current calendar and then recreating new calendar items on top of it.
Open Outlook by clicking on the "Outlook" shortcut icon that is either pinned to the "Start" menu or is located on the desktop. If there is no "Outlook" shortcut located on your computer, click on "Start" and "All Programs." After the "Programs" list opens, choose "Microsoft Office" and then "Microsoft Outlook."
Click on the "Calendar" icon at the top of the page after Outlook opens. This will switch Outlook from displaying the email screen--which is its default-- to displaying the calendar screen.
Move your cursor to "Current View." A new menu will open that includes the entry "View." Click "View." When the next sub-menu opens, move the cursor to "By Category" and click.
Wait while a list of all of your calendar items populates. This should only take a moment. When the list appears, use the key sequence "Ctrl" + "A" on your keyboard to select all of the calendar entries in the list.
Select the "DEL" or "Delete" key on your keyboard and all of the calendar entries will be deleted.
Click "OK" to close this window and take a look at your calendar. There should now be no entries on the calendar page.
Tips & Warnings
- Reduce the size of your "Deleted Items" folder by emptying the folder after deleting the calendar entries.
