Delete Old Meetings Using List View in Classic Outlook

The most efficient way to find and delete old calendar items in bulk is by changing your calendar view to a list format.

Switch to Calendar View

Open Microsoft Outlook and click on the Calendar icon at the bottom left of your navigation pane.

Change View to List

Navigate to the 'View' tab on the top ribbon, click on 'Change View', and select 'List' from the drop-down menu.

Sort and Delete

Click the 'Start' column header to sort your meetings chronologically. Hold down the Shift key to select multiple old meetings, then press the Delete key on your keyboard.

Frequently Asked Questions

Does deleting an old calendar meeting send a cancellation to attendees?

If the meeting is in the past, deleting it normally won't trigger a cancellation notice to attendees. However, if it does prompt you, you can choose to 'Delete without sending a cancellation' to avoid notifying others.

Can I recover calendar events if I accidentally deleted them?

Yes. Deleted calendar items are temporarily moved to the 'Deleted Items' folder in your Outlook mailbox. You can go to this folder, find the deleted meeting, right-click it, and move it back to your Calendar folder.

Why is my Outlook mailbox still full after deleting old calendar items?

Calendar items usually take up very little space compared to emails with attachments. To effectively free up storage space, you should empty your 'Deleted Items' folder, check your Sent Items, and filter your inbox to delete emails with large attachments.
