This rule generally applies to all Outlook versions, including Outlook 2019, 2016, 2013, 2010, and older.
Whether you delete the email from Inbox, Sent Items, Drafts, or any other folder, the deleted email always goes to the Deleted Items folder. When you delete an Outlook email or another item such as a calendar invite, contact, task, or folder by pressing the delete key or using Right-Click and selecting the Delete option, the email goes to the Deleted Items folder.
