The fastest way to delete many emails at once

You can select and delete multiple emails in Outlook in three ways: by clicking checkboxes next to each message, by using keyboard shortcuts to select a range, or by using the search box to narrow down to just the emails you want gone. The method you choose depends on whether the emails are grouped together or scattered across different dates and folders.

The simplest approach for emails sitting next to each other is to click the checkbox next to the first one, hold Shift, and click the checkbox next to the last one. This selects everything in between. Then click the Delete button (or press the Delete key). For emails scattered throughout your inbox, search for a word or sender name first — this shrinks your view to only matching messages — then select all of those results at once and delete them together.

Key Takeaways

  • Click the checkbox next to the first email you want to delete, hold Shift, then click the checkbox next to the last email to select a block of messages at once.
  • Use the search box to find emails by sender, subject, or date, then delete all the search results together without affecting other messages.
  • Click the checkbox at the very top of the email list (next to "From") to select every email on the current page, then delete them all in one action.
  • Deleted emails go to your Trash folder first, so you can recover them if you change your mind within 30 days.
  • Permanently removing emails from Trash requires a separate step — straightforward deleting them once moves them to Trash, not out of Outlook entirely.

Selecting emails that sit next to each other

Open Outlook and navigate to the folder holding the emails you want to delete — usually your Inbox. Look at the left side of each email row. You will see a small empty checkbox.

Click the checkbox next to the first email you want to delete. A checkmark appears. Now hold down the Shift key on your keyboard and click the checkbox next to the last email in the group you want to delete. Outlook selects every email between the first and last one you clicked, and you will see checkmarks in all of them.

Once the emails are selected, look at the top of the email list. You will see a Delete button (it often looks like a trash can icon). Click it. All the selected emails move to your Trash folder. If you delete by mistake, go to your Trash folder and move them back to Inbox by right-clicking and selecting "Move" or dragging them back.

Using search to find and delete scattered emails

If the emails you want to delete are not grouped together — for example, messages from one sender spread across weeks, or emails with a specific word in the subject line — use the search box to gather them first. This way you delete only what you want without touching anything else.

At the top of Outlook, find the search box (it usually says "Search" or has a magnifying glass icon). Click it and type what you are looking for: a sender's name, a subject line, a date range, or a word that appears in the emails. Press Enter. Outlook shows only the emails that match your search.

Now click the checkbox at the very top of the email list, next to the column headers. This selects every email in your search results. Click the Delete button. All of them move to Trash at once. This method is especially useful for clearing out promotional emails from one sender or old messages about a topic you no longer need.

Selecting all emails on the current page

If you want to delete everything you see on the screen right now — for instance, clearing out your entire Inbox — click the checkbox at the very top of the email list, in the header row next to "From" or "Subject". This selects every email currently visible on that page.

Be careful with this method: it selects only the emails shown on your screen, not every email in the folder. If your Inbox has 500 emails but only 50 fit on one page, clicking the top checkbox selects only those 50. If you want to delete more, you will need to scroll down and repeat the process, or use the search method instead to narrow down first.

Once you have selected the emails, click Delete. They move to Trash.

Understanding Trash and permanent deletion

When you click Delete, emails do not leave Outlook when ready. They move to your Trash folder (sometimes called Deleted Items). This is a safety net: if you realize you deleted something by mistake, you can go to Trash, find the email, and move it back to Inbox.

Emails stay in Trash for 30 days by default in most Outlook setups. After 30 days, Outlook removes them permanently. If you want to delete something right now without waiting, go to your Trash folder, select the email, and press Delete again. This permanently removes it from Outlook.

To empty your entire Trash folder at once, right-click on the Trash folder in the left sidebar and select "Empty Folder". This removes everything in Trash permanently, so use this only when you are sure you do not need any of those deleted emails.

Avoiding accidental deletion of important emails

Before you select and delete a large batch of emails, take a moment to double-check that you are in the right folder and that your search is correct. A common mistake is selecting emails in the wrong folder or deleting search results that include something you meant to keep.

If you are using search, scan the results on screen before selecting all of them. If you are selecting a range with Shift-click, make sure the first and last emails you click are actually the ones you want to delete — everything in between will be selected too. Once you are confident, proceed with the delete.

Another safeguard: if you are deleting a very large number of emails (hundreds at once), delete them in smaller batches. This way, if something goes wrong, you have not lost everything at once and you can recover some of them from Trash before the 30-day window closes.

Frequently Asked Questions

Can I undo a delete if I already emptied my Trash folder?

No. Once you empty Trash, the emails are gone from Outlook permanently. If you have not emptied Trash yet, go to your Trash folder, find the email, and move it back to Inbox. After Trash is emptied, recovery is not possible through Outlook itself.

What if I delete emails by mistake and do not notice for weeks?

If it has been less than 30 days since you deleted them, check your Trash folder. The emails should still be there. If it has been more than 30 days, Outlook has removed them permanently and they cannot be recovered.

Can I delete emails from multiple folders at the same time?

No. You must be in one folder at a time to select and delete emails from it. If you want to delete emails from multiple folders, repeat the process in each folder separately, or use search to find all matching emails across folders, then delete the results.

Does deleting an email also delete it from my phone or other devices?

Yes, if your phone is set up to sync with your Outlook account. When you delete an email on your computer, it moves to Trash on all your devices. The same 30-day recovery window applies across all of them.

What is the difference between Delete and Archive?

Delete moves emails to Trash, where they stay for 30 days before being removed. Archive moves emails to a separate folder (usually called Archive or All Mail) where they stay permanently but are hidden from your main Inbox. Archive is useful for keeping old emails without deleting them.
