Deleting mail in Outlook removes it from your inbox, but the message goes to your Deleted Items folder first

When you delete a message in Outlook, it does not disappear when ready. Instead, it moves to a folder called Deleted Items (or Trash on some versions). From there, you can still recover it if you change your mind. To remove mail permanently, you need to empty the Deleted Items folder or use Outlook's permanent delete function, which skips the folder entirely.

The steps differ slightly depending on whether you use Outlook on the web, Outlook desktop software, or Outlook on your phone. All three let you delete messages, but the permanent delete option is easiest on desktop and web versions.

Key Takeaways

  • Pressing Delete moves a message to Deleted Items; it is still recoverable from there for 30 days or longer depending on your settings.
  • To delete permanently on desktop or web, select the message and press Shift+Delete instead of just Delete.
  • Emptying your Deleted Items folder removes all messages in that folder at once, which is faster if you want to clear out many old deletions.
  • Deleted messages may still be backed up on your email provider's servers even after you empty Deleted Items, depending on your account type and recovery settings.

Delete a single message on Outlook desktop

Open Outlook on your computer and find the message you want to delete. Click on it once to select it, then press the Delete key on your keyboard. The message moves to your Deleted Items folder.

If you want to skip Deleted Items and remove the message permanently right away, select it and press Shift+Delete instead. Outlook will ask you to confirm; click Yes. The message is then removed from your mailbox, though it may still exist in your provider's backup systems.

Delete a single message on Outlook web

Log into Outlook.com or your organization's Outlook web version. Find the message in your inbox or any folder. Click the checkbox next to the message to select it, then look for the trash or delete icon in the toolbar at the top. Click it.

The message moves to Deleted Items. To delete it permanently from there, open your Deleted Items folder, select the message again, and click the delete icon a second time. Outlook will ask you to confirm the permanent deletion.

Delete messages on Outlook mobile

Open Outlook on your phone or tablet. Find the message you want to remove. On iPhone or iPad, swipe left on the message; on Android, press and hold it. A menu appears with a delete or trash option. Tap it.

The message goes to Deleted Items. To permanently remove it, open Deleted Items, find the message, and tap delete again. Mobile versions do not always show a confirmation dialog, so the message may be removed when ready.

Empty your entire Deleted Items folder at once

If you have many old messages you want to clear out, emptying Deleted Items is faster than deleting them one by one. On desktop Outlook, right-click the Deleted Items folder in the left sidebar and select Empty Deleted Items Folder. Outlook asks you to confirm; click Yes. All messages in that folder are permanently removed.

On Outlook web, open your Deleted Items folder, then look for a button or menu option that says Empty Folder or similar (the exact wording varies by version). Click it and confirm. On mobile, you may not have an empty-all option; instead, select multiple messages by tapping and holding, then delete them together.

Recover a deleted message before it is gone for good

If you deleted a message by mistake, open your Deleted Items folder. Find the message, right-click it (or press and hold on mobile), and select Move or Restore. Choose the folder where you want it to go — usually your Inbox. The message returns to that folder.

This works as long as the message is still in Deleted Items. Once you empty Deleted Items or permanently delete the message with Shift+Delete, recovery becomes much harder. Some email providers keep deleted messages in a hidden recovery area for 30 days or more, but retrieving them requires contacting support and providing proof you own the account.

Understand what happens to deleted mail on your provider's servers

Deleting a message from Outlook removes it from your device and your mailbox, but your email provider — Microsoft, Google, your workplace, or whoever runs your email — may keep a copy for backup or legal reasons. This is especially true for work email accounts, which are often subject to retention policies that keep deleted messages for months or years.

If you use a personal Outlook.com account, Microsoft typically keeps deleted messages for 30 days in a recovery system. After that, they are removed from their servers. If you use Outlook through your employer or school, ask your IT department about their deletion and backup policies, because those vary widely and may be much longer.

Frequently Asked Questions

Can I recover a message after I empty Deleted Items?

It depends on your email provider. Microsoft keeps deleted messages for about 30 days in a recovery system, but you cannot access it yourself — you have to contact Microsoft support and prove you own the account. For work email, contact your IT department; they may be able to recover it from backups, but policies vary.

Does deleting mail free up storage space?

Deleting a message moves it to Deleted Items, which still counts toward your storage limit. You free up space only when you empty Deleted Items or permanently delete the message. If you are running out of storage, emptying Deleted Items is usually the fastest way to recover space.

What is the difference between Delete and Shift+Delete?

Delete moves the message to Deleted Items, where you can still see and recover it. Shift+Delete removes it when ready without going to Deleted Items. Both methods may leave copies on your provider's backup servers, but Shift+Delete is faster if you want the message out of your mailbox right away.

Will my deleted messages show up in a search?

Once a message is in Deleted Items, Outlook's search usually excludes it by default. If you permanently delete it or empty Deleted Items, it will not appear in search results. However, if your email provider keeps backups, they may still be searchable by your IT department or support staff.

Can I set Outlook to automatically delete old messages?

Yes, but the feature name and location vary by version. On desktop Outlook, look in Settings for an AutoArchive or retention policy option. On Outlook web, check Settings for a similar feature. These tools can move or delete messages older than a certain date automatically, though you should test the settings on a small folder first to make sure they work the way you expect.
