How to Permanently Delete Emails From Outlook

If your mailbox storage is filling up, it’s time to permanently delete emails in Outlook rather than let them consume space in the Deleted Items folder. We’ll walk you through cleaning up Outlook and using Clean Email for flexible ways to delete and manage messages in a secure environment.

What You Should Know About Outlook Deleted Items Folder

What many people don’t realize is that deleting an email in Outlook doesn’t remove that email for good. When you delete a message, this actually moves it to a Deleted Items folder.

The reason for this is that it gives you an opportunity to recover deleted emails in Outlook that you may delete by mistake. While this can be helpful, those messages in the Deleted Items folder still consume storage space in your Outlook mailbox.

If you want to permanently delete Outlook emails, you must either delete the messages and then empty the Deleted Items folder or take a different step to remove the emails immediately and skip that folder.

While you’ll learn how to delete emails in Outlook completely, you’ll also see how to both automatically and manually remove them, individually or in bulk, using Clean Email. These other methods give you more flexibility over the emails you want to remove as well as a clean Outlook inbox.

Then, confirm you are aware that choosing Delete is irreversible, and enjoy achieving Inbox Zero.

  2. Select Create RuleSelect Create Rule

Along with Clean Email’s Suggestions and Auto Clean features, you can take advantage of additional tools to keep your Outlook inbox tidy including Unsubscriber and Smart Folders.

With Unsubscriber, you can stop receiving newsletters and promotional emails that you end up deleting anyway. This saves you time from permanently removing these emails later because you’ll no longer receive them at all.
