Remove Completed Tasks Using the Tasks View

This method filters your task list to only show completed items, making it easy to delete them individually or in bulk.

By switching to the 'Completed' view within the Tasks module, you isolate finished items from your active workload. This prevents accidental deletion of pending tasks.

1
Open the Tasks Module

Launch Microsoft Outlook and click on the 'Tasks' icon (typically represented by a clipboard with a checkmark) located in the bottom-left navigation pane.

2
Switch to the Completed View

In the Tasks pane, navigate to your Current View settings in the ribbon and select the 'Completed' view to filter and display only your finished tasks.

3
Delete the Desired Tasks

Right-click on the completed task you wish to remove and select 'Delete' from the context menu. To delete multiple tasks at once, hold the Ctrl key while selecting them, then right-click and choose 'Delete'.

4
Confirm Deletion

If Outlook prompts you with a warning that the item will be permanently deleted or moved to the Deleted Items folder, click 'Yes' or 'OK' to confirm the action.

Frequently Asked Questions

Can I hide completed tasks instead of permanently deleting them?

Yes. Instead of deleting them, you can change your view to the 'Active' view. Go to the View tab on the ribbon, click Change View, and select 'Active'. This automatically hides any tasks marked as completed while keeping them safely in your records.

Why are my completed tasks not showing up in the 'Completed' view?

If tasks are missing from the Completed view, your current view settings may have active filters blocking them. Go to the View tab, select View Settings, click on 'Filter', and click 'Clear All' to reset your filters.

Can Outlook automatically delete my completed tasks?

While Outlook cannot automatically delete tasks the moment they are completed, you can use the AutoArchive feature. Right-click your Tasks folder, select Properties, and go to the AutoArchive tab to configure settings that automatically move or delete older completed tasks.
