How to Automatically Empty Trash when Exiting Outlook 2011 for Mac

Outlook 2011 for Mac allows you to schedule tasks that help keep Outlook running efficiently. This is a incredibly useful and an often underused feature.

For example, when you manually delete email throughout your day, those items are stored in the Deleted Items folder. Over time, this folder can grow very large and can slow down Outlook for Mac. In order to fix the issue, you must manually empty your Trash after you delete an email. Most people delete an email and never do the latter. Fortunately, Outlook has a solution that automatically deletes your trash when you exit the program.

Here’s how to set it up.

Enable the Existing Empty Trash Schedule

Open Outlook from the Apple dock as shown in Figure A.

Create a New Empty Trash Schedule from Scratch

  • Open Outlook and Select Tools | Run Schedule and choose Edit Schedule (See Figure B).
  • Click the + sign and add a title such as Delete Trash on Exit.
  • Under When choose On Quit.
  • Under Action choose Delete Mail and choose the Deleted items folder. Placing a 0 for Older than Days will just delete mail on exit. In this example, I chose to delete all mail older than 7 days.
