You want to find and use the Sweep feature in the new Outlook for Windows to automatically clean your inbox. Sweep lets you move, delete, or keep only the latest message from a sender with a single rule. This article explains where to find Sweep settings, how to create and manage rules, and the practical limits you will encounter when using them.
Key Takeaways: Sweep Rules in New Outlook
- Inbox > Select message > Sweep button: Opens the Sweep menu where you choose an action and apply it to all messages from that sender.
- Settings > Mail > Sweep: Lists all active Sweep rules and lets you edit, disable, or delete each one.
- 50-rule limit: You can create a maximum of 50 Sweep rules per mailbox, and each rule applies only to one sender.
What Sweep Does and How It Works in New Outlook
Sweep is a built-in mail management feature in new Outlook that lets you apply a bulk action to all messages from a specific sender. When you run a Sweep, Outlook creates a server-side rule that runs on Exchange Online. The rule does not require Outlook to be open to execute.
Sweep offers four actions:
- Delete all messages from the sender.
- Move all messages from the sender to a specified folder.
- Keep only the latest message from the sender and delete the rest.
- Delete messages older than 10 days from the sender.
Sweep rules apply only to messages that arrive in your Inbox. Messages already moved to another folder or deleted are not affected. Each rule targets a single sender address. You cannot create a Sweep rule that covers multiple senders or uses domain-level matching.
Prerequisites for Using Sweep
You need an Exchange Online mailbox. Sweep rules are server-side and do not work with POP3, IMAP, or on-premises Exchange mailboxes. The new Outlook for Windows must be installed and configured with your Exchange account. Sweep is available in both the new Outlook and Outlook on the web.
Where to Find and Create Sweep Rules
You can create a Sweep rule directly from any message in your Inbox. You manage existing rules in the Settings panel.
Create a Sweep Rule from a Message
- Open new Outlook and go to your Inbox
Make sure you are viewing the Inbox folder where the sender’s messages appear. - Select any message from the sender you want to manage
Single-click the message to highlight it. Do not open it in a separate window. - Click the Sweep button in the toolbar
The Sweep button appears in the Home tab of the ribbon. Its icon shows a broom. If you do not see it, click the three-dot menu in the toolbar and choose Sweep. - Choose an action from the dropdown menu
Select one of the four options: Delete All, Move to Folder, Keep the Latest, or Delete Older Than 10 Days. - Confirm the action in the dialog that appears
Outlook shows a preview of how many messages will be affected. Click OK to apply the rule immediately and move or delete the matching messages.
Manage Existing Sweep Rules in Settings
- Click Settings in the top-right corner
The gear icon opens the Settings panel. - Go to Mail > Sweep
In the left navigation, expand Mail and select Sweep. The page lists all active Sweep rules grouped by sender. - Edit, disable, or delete a rule
Click on any rule to view its details. You can change the action, the target folder, or disable the rule. To remove it, click the Delete icon. - Create a new rule from Settings
Click the Add new sweep rule button. Enter the sender email address, choose an action, and select a destination folder if applicable. Click Save.
Practical Limits of Sweep Rules
Sweep rules have several limits that affect how you can use them in a busy mailbox. Understanding these limits helps you avoid unexpected behavior.
Rule Count Limit
You can create a maximum of 50 Sweep rules per mailbox. This limit applies to the total number of rules across all folders. If you reach 50, you must delete an existing rule before creating a new one. The count includes both enabled and disabled rules.
Sender Scope Limit
Each Sweep rule applies to exactly one sender email address. You cannot create a rule that covers an entire domain. For example, a rule targeting @newsletter.com will not apply to messages from newsletter@company.com. You must create a separate rule for each individual sender.
Folder Destination Limit
When you use the Move to Folder action, you must select a folder that already exists in your mailbox. Sweep does not create a new folder. The destination folder must be in the same mailbox. You cannot move messages to a shared mailbox or a public folder.
Time-Based Actions
The Delete Older Than 10 Days action uses the message received date. It does not consider the sent date or the last modified date. The rule runs once when you create it. After that, it does not automatically apply to new messages. You must run Sweep again manually or create a separate rule with the same action to apply it to future messages.
Rule Execution Frequency
Sweep rules execute only when you manually trigger them from the message list or from Settings. They do not run automatically on a schedule. If you want a rule to apply continuously, you must use a regular Inbox rule instead of Sweep.
Common Mistakes and Limitations to Avoid
Sweep Does Not Work on IMAP or POP Accounts
If you use an IMAP or POP3 account, the Sweep button is grayed out. Sweep requires an Exchange Online mailbox. For non-Exchange accounts, use client-side rules or manual folder organization.
Deleted Messages Cannot Be Recovered via Sweep
When you use Delete All or Delete Older Than 10 Days, messages are moved to the Deleted Items folder. If you need to recover them, go to Deleted Items and move them back. There is no undo for Sweep actions. Check the preview dialog before confirming.
Sweep Rules Do Not Override Inbox Rules
If you have an Inbox rule that moves messages from a sender to a folder, Sweep will not find those messages in the Inbox. Sweep only scans the Inbox folder. Messages moved by an Inbox rule are skipped. To avoid this, remove or edit the conflicting Inbox rule.
Shared Mailbox Limitations
Sweep rules created in a shared mailbox apply to that mailbox, not to your primary mailbox. You must be signed in to the shared mailbox directly in new Outlook to create or manage its Sweep rules. Sweep rules from a shared mailbox do not appear in your primary mailbox settings.
Sweep vs Inbox Rules: Key Differences
| Item | Sweep | Inbox Rules |
|---|---|---|
| Rule creation | From a message or Settings | Settings > Mail > Rules |
| Sender scope | One sender per rule | Multiple senders, domains, or conditions |
| Execution | Manual trigger only | Automatic on arrival |
| Rule limit | 50 rules per mailbox | 256 rules per mailbox |
| Server-side | Yes, runs on Exchange Online | Yes, runs on Exchange Online |
| Recovery after delete | From Deleted Items folder | From Deleted Items folder if rule deletes |
Use Sweep for quick, one-time cleanup of a specific sender. Use Inbox rules for ongoing automation that runs every time a new message arrives.
You can now find the Sweep button in the new Outlook toolbar and create a rule for any sender in your Inbox. The 50-rule limit means you should reserve Sweep for your most frequent senders. For ongoing automation, switch to Inbox rules in Settings > Mail > Rules. If you need to apply an action to multiple senders at once, consider using a Quick Step instead.
