- Question from Quora
Got way too many emails clogging your inbox? You're not alone. Whether you’re decluttering or just hitting the reset button, learning how to delete all emails on Outlook can be a total game-changer.
Let’s walk you through the exact steps — no fluff, no tech jargon, just simple, practical advice you can follow right now.
Why You Might Want to Delete All Emails on Outlook
Let’s be real — inbox overload is stressful. Here’s why mass deletion might be the right move.
Overwhelming Inbox
Ever opened Outlook and immediately closed it again because the email count gave you anxiety? Yeah, we’ve all been there. Sometimes, starting fresh is the best fix.
Running Out of Storage
Outlook (especially if you’re using it with a free Microsoft account) has storage limits. Once you’re out of space, incoming emails bounce. Not ideal, right?
Starting Fresh
Moving jobs? Shifting to a new email system? Wiping your mailbox clean gives you a clean slate to work with — no baggage, no spam.
Understanding How Outlook Stores Emails
Before diving in with the delete button, it helps to understand where Outlook keeps all your emails.
Outlook Desktop vs. Web Version
Outlook comes in many flavors: desktop app (for Windows and Mac), web app (OWA), and the mobile app. Each version handles bulk actions a bit differently.
Folder Structure: Inbox, Spam, Archive, and More
Outlook doesn’t just dump all your emails into the inbox. You’ve also got folders like Sent, Drafts, Spam, Trash, and Archive — each requiring its own cleanup.
How to Delete All Emails on Outlook
Alright, let’s get to the juicy part: the how-to.

Method 3: Use Outlook Mobile App to Delete All Emails
Outlook’s mobile app doesn’t have a “select all” option, unfortunately. But here’s a workaround:
1. Tap and hold to select one message.
2. Tap other messages to select more (tedious, but it works).
3. Tap the trash icon.
4. Clear out the trash folder to finish the process.

How to Delete All Emails in Specific Folders
Maybe you don’t want to go nuclear on your whole mailbox — just clean up certain spots.
Clear Inbox Only
Just head to the Inbox, press Ctrl/Command + A, and delete.
Empty Spam and Trash Automatically
Go into Settings > Mail > Junk Email or Trash, and turn on automatic clearing options. You can set a schedule to delete emails older than 30 days.
How to Delete All Emails from a Specific Sender
Want to target a spammy sender?
1. Type their email in the search bar.
2. Select all results using the checkbox.
3. Hit Delete.
Bonus tip: Create a rule to auto-delete future emails from that sender.
Tips to Prevent Email Overload in the Future
Prevention is better than cure. Here’s how to stay ahead of the clutter.
Unsubscribe from Newsletters
That newsletter you haven’t read in 6 months? Time to let it go. Use tools like Unroll.Me or do it manually at the bottom of emails.
Use Email Rules and Filters
Set up automatic sorting. For instance, filter promotions or updates into separate folders, so your primary inbox stays clean.
Archive Instead of Delete
Not sure if you’ll need that email someday? Archiving is a great middle-ground between hoarding and deleting.
What Happens After Deleting All Emails?
Before you go on a deletion spree, let’s talk consequences.
Can You Recover Them?
Yes — but only if they’re still in the Deleted Items folder. Once that’s emptied, they’re gone unless you have backups.
Where Do Deleted Emails Go?
They move to the Deleted Items or Trash folder first. If you empty that, they’re permanently deleted from your account.
Common Issues and Troubleshooting
Sometimes Outlook plays hardball. Here’s how to deal.
Outlook Freezes When Deleting Too Many Emails
Try deleting in smaller batches. Outlook can get overwhelmed if you select 10,000+ emails at once.
Deleted Emails Keep Coming Back
This can be a syncing issue. Make sure you're online, and your account is properly syncing with the server.
