To solve the issue of emails automatically being sent to the deleted items folder in Outlook, you can take the following steps:

1. Check the settings of Rules & Alerts to ensure no Outlook rule has been set up to move the emails to the deleted items folder.
2. Ensure Outlook is set to send and receive emails. To do this, go to Send/Receive tab and click on Send/Receive All Folders.
3. Check the Outlook's Junk Email Filter settings if you are using a third-party anti-spam filter.
4. Try creating a new Outlook email profile.
