What Is Sweep in Outlook? How to Use It (and Its Limits)

Sweep is a built-in Outlook feature that deletes, or moves, all the emails from one sender in a folder at once. It can also keep doing that automatically for the sender’s future emails. It’s available in Outlook.com (including Hotmail and Live), Outlook on the web, and new Outlook for Windows. Classic Outlook and the Outlook mobile apps don’t have it.

Here’s what each Sweep option does, how to use it, how to undo it, and where it runs out of road.

What Sweep does: the four options

Select an email and click Sweep, and Outlook offers four choices for that sender. The wording varies slightly between versions:

Option	What it does	Keeps running?
Delete all messages from the Inbox folder	Clears everything that sender has sent to the current folder	No, one-time
Delete all messages from the Inbox folder and any future messages	Clears it now and removes their new emails as they arrive	Yes
Always keep the latest message and delete the rest	Keeps only their most recent email (handy for daily deals or statements)	Yes
Always delete messages older than 10 days	Lets their emails sit for 10 days, then removes them	Yes

By default, swept emails go to Deleted Items. Using the Move to option, you can send them to another folder instead (an “Old newsletters” folder, for example), which turns Sweep into a quick filing tool as well as a delete button.

How to use Sweep in Outlook

Open the Inbox (or a subfolder) and select an email from the sender you want to clear.
Select Sweep on the toolbar. In new Outlook it’s on the Home tab. If your window is narrow, look under the … (more options) menu.
Choose one of the four options above. To file the emails rather than delete them, change Move to.
Select Sweep to confirm.

The one-time option runs straight away. The ongoing options create a sweep rule, which Microsoft runs on its servers once a day. That means it keeps working when Outlook is closed, but not instantly.

Which versions of Outlook have Sweep?

Outlook version	Sweep?
Outlook.com (Hotmail, Live, MSN)	Yes
Outlook on the web (Microsoft 365 work and school)	Yes
New Outlook for Windows	Yes
Classic Outlook for Windows	No, but sweep rules you created elsewhere still run
Outlook for Mac	No
Outlook app on iPhone and Android	No. Open Outlook.com in your phone’s browser instead

Sweep also isn’t available from the Junk Email, Drafts, Sent Items, or Deleted Items folders.

How to see, change, or remove Sweep rules

If a sender’s emails keep vanishing and you don’t remember why, a sweep rule is the likely cause. To manage them:

Open Settings (the gear icon).
Go to Mail → Sweep to see your sweep rules. Turn them off or delete them there.
Also check Mail → Rules: the “delete any future messages” option can show up there as an ordinary rule.

To get back emails Sweep has already removed, open Deleted Items (or the folder you moved them to), select them, and move them back to your Inbox.

Sweep vs rules vs blocking vs unsubscribing

Tool	Best for	Watch out for
Sweep	Clearing one sender’s pile, and optionally their future mail	One sender and one folder at a time; rules run daily
Rules	Acting on new mail instantly with detailed conditions	More setup; doesn’t clean up existing mail by itself
Block	Spam and senders that ignore unsubscribe requests	Sends future mail to Junk; does nothing about old mail
Unsubscribe	Stopping legitimate newsletters at the source	Old emails stay until you delete them

The most effective combination is to unsubscribe, then Sweep. Unsubscribing stops new mail and Sweep clears the backlog. See how to mass unsubscribe from emails in Outlook and block vs unsubscribe in Outlook.

Where Sweep falls short

Sweep is great for a few known offenders, but it struggles with a real cleanup:

One sender at a time. Twenty noisy senders means twenty separate sweeps.
One folder at a time. It clears the folder you’re in, not the same sender’s mail across your whole mailbox.
It doesn’t tell you who to sweep. Outlook never ranks senders by volume, so you’re guessing where to start. See how to see who emails you the most in Outlook.
It doesn’t unsubscribe you. The sender keeps your address and keeps mailing. Sweep just keeps deleting.
The 10-day setting is fixed. You can’t choose 30 days or a year.
It isn’t instant, and isn’t everywhere. Rules run once a day, and you can’t create them in classic Outlook, on a Mac, or in the mobile apps.

Sweep for many senders at once

Not to be confused with Outlook’s Sweep: Sender Sweep is our independent tool. It isn’t made by Microsoft.

Sender Sweep is built for the cleanup Outlook’s Sweep can’t do in one go:

It scans your whole mailbox, across every folder, and ranks every sender by how many emails they’ve sent and how many you’ve read.
You can then select dozens or hundreds of senders at once and delete, archive, or unsubscribe from all of them in a single action.
Deleted emails go to Deleted Items, just like Sweep.
It works with personal Outlook.com, Hotmail, and Live accounts.
It runs entirely in your browser, so your email never touches our servers.
The free plan includes unlimited scanning and 500 deletes a month.

Many people use both: Sender Sweep for the big initial clear-out, then Outlook’s Sweep rules to keep a few persistent senders under control.

FAQ

What does Sweep do in Outlook? It deletes or moves every email from one sender in the current folder. It can also keep doing so automatically: removing their future emails, keeping only their latest one, or removing anything of theirs older than 10 days.

Why don’t I see Sweep in Outlook? You’re probably in classic Outlook for Windows, Outlook for Mac, or the mobile app, none of which have it. Use Outlook.com or new Outlook. Sweep is also hidden in the Junk Email, Drafts, Sent Items, and Deleted Items folders.

Does Sweep delete future emails? Only if you choose an ongoing option, such as “delete any future messages”, “keep the latest”, or “older than 10 days”. The plain “delete all” option is one-time.

Can I undo a Sweep? Yes. Swept emails go to Deleted Items by default, so you can move them back. To stop future sweeping, delete the rule under Settings → Mail → Sweep.

Does Sweep unsubscribe me from emails? No. It only deletes or moves emails you receive. To stop a newsletter at the source, use the Unsubscribe button at the top of the email.

Is Sender Sweep part of Outlook? No. Sender Sweep is an independent web app for bulk-cleaning Outlook mailboxes. Outlook’s Sweep is Microsoft’s built-in, one-sender-at-a-time feature.
