Hey, thanks for your feedback! This option will be added back to OWA in the next couple months. We’re working on improving the service that powers Clean Up, and then we’ll add this option back!
I can no longer find the very useful Clean Up Mailbox page that used to be found Settings>Mail>Options>Clean up mailbox. Nor could I find a similar feature in the new Outlook.David supported this idea ·
