Outlook Mailbox Rules: How to Create and Manage Them

Create a mailbox rule in Outlook by choosing a condition, such as who sent a message or words in its subject, then assigning an action, such as moving it to a folder or marking it as read. The controls differ slightly between new Outlook, classic Outlook for Windows, Outlook for Mac, and Outlook on the web, so use the instructions for the version you have. Rules can automatically handle incoming messages and reduce routine inbox sorting.

What You’ll Need

An Outlook account and access to the mailbox where you want the rule to run.
A clear idea of the messages to match and what Outlook should do with them. If you plan to move messages, create the destination folder first.
For a forwarding rule, the recipient’s correct email address. Your organization may restrict automatic forwarding.

Rules generally apply to new incoming mail after you create them. They do not always process messages already in your inbox automatically; classic Outlook for Windows includes an option to run a rule on existing messages in some cases.

Step-by-Step

Identify your Outlook version. New Outlook for Windows and Outlook on the web have a similar settings-based rules page. Classic Outlook for Windows has a Rules Wizard. Outlook for Mac has its own Rules settings, and available options can vary with the account type. In classic Outlook for Windows, the older interface usually has a File tab and a full desktop ribbon; new Outlook has a Settings gear and a more web-like layout.
Open the rules controls. In new Outlook for Windows or Outlook on the web, select the Settings gear, then choose Mail > Rules. Select Add new rule. In classic Outlook for Windows, go to Home > Rules > Manage Rules & Alerts, then select New Rule. In Outlook for Mac, open Outlook > Settings (or Preferences in some builds) > Rules. Choose the relevant account if Outlook asks which mailbox to configure.
Name the rule and choose a condition. In new Outlook or the web, enter a name in the rule name field, then select a condition from the menu, for example From, Subject includes, or To. In classic Outlook, choose a starting template or select Apply rule on messages I receive, then select Next and tick the condition or conditions you want. Select the underlined values in the wizard to specify a sender, phrase, or other detail. Be precise: a condition for a sender’s full address is usually narrower than one for a common display name.

If you choose more than one condition, Outlook generally requires a message to satisfy all selected conditions. For example, From a particular address plus Subject includes invoice matches messages from that sender whose subject also contains the phrase. If you want a rule to catch either of two senders, use an option that supports multiple senders in the same condition, or create separate rules and test them.
Choose the action. Select what Outlook should do when a message matches. Common actions include moving the message to a folder, assigning a category, marking it as read, flagging it, deleting it, or forwarding it. In new Outlook and the web, select an action in the Add an action menu and fill in any required details, such as the folder or forwarding address. In classic Outlook, select Next after setting the conditions, tick the action, and select its underlined value to configure it.

For a move action, select the destination folder carefully. For forwarding, review the address before saving, and avoid forwarding sensitive or work messages to an external account unless your organization permits it. In classic Outlook, you can also choose actions such as playing a sound or displaying a desktop alert, depending on the account and rule type.
Add exceptions if needed. An exception prevents the rule from acting on particular messages even when they meet its condition. For instance, a rule that moves mail from a supplier to a project folder could exclude messages marked as high importance. In the settings-based editor, use Add an exception if it is available. In classic Outlook, select Next after choosing actions, then tick the exception and specify its value. Keep exceptions focused; too many can make it difficult to understand why a message did not match.
Set rule order and processing options. If you have multiple rules, their order can affect the final result. In new Outlook or the web, use the move-up and move-down controls on the Rules page when available. In classic Outlook, select a rule in Manage Rules & Alerts and use the arrows to change its position. Where offered, Stop processing more rules means Outlook will not apply later rules to a message after this rule runs. Use it only when you want this rule to take precedence; otherwise, a later rule might need to categorize or move the same message too.
Save the rule and check the result. Select Save in new Outlook or the web, or Finish in the classic Rules Wizard, then apply the changes if Outlook prompts you. Send yourself a test message that meets the conditions, or ask the sender to send one. Check both the destination folder and the original inbox, and confirm that the intended action occurred. If the rule is meant to handle existing mail, look for a Run rule now option in the rules interface; availability and scope depend on the Outlook version and account.
For classic Outlook, review the wizard summary. Before selecting Finish, check the rule description at the bottom of the wizard. It should state the right conditions, actions, and exceptions. You can select an underlined phrase in that summary to edit it. If you want the rule to run immediately on messages already in a folder, enable the option to run it on existing messages when the wizard offers it, and choose the folder. This option is not the same as automatically applying every rule to all historical mail.

Common Mistakes

Using a condition that is too broad. A rule based on a short subject word such as report may catch unrelated messages. Use distinctive wording, the sender address, or a combination of conditions, then test with representative mail.
Expecting a new rule to reorganize old messages. Most rules are primarily for incoming mail. Check for a run-now option or move existing messages manually; do not assume that saving the rule cleans up the inbox history.
Creating overlapping rules without checking their order. One rule may move a message before another can categorize it, or Stop processing more rules may prevent later actions. Review the order and use a test message to check how the rules interact.
Choosing the wrong folder or address. A small selection error can send messages somewhere unexpected. Verify the destination folder and any forwarding recipient before saving, especially for confidential mail.
Assuming every rule runs when Outlook is closed. Many server-side rules can run while you are offline, but some classic Outlook rules rely on the desktop app being open. The wizard may label a rule as client-only when it needs Outlook on your computer.

Tips

Use short, descriptive names such as Supplier invoices to Finance or Newsletters to Reading. Clear names make it easier to review, reorder, or disable rules later.
Prefer moving routine mail into folders over deleting it if you may need to refer to it. You can use categories or flags when keeping the message visible in the inbox matters.
Start with one condition and one action, test the result, and only then add exceptions or more complex logic. This makes mistakes easier to diagnose.
Periodically review the Rules page or Manage Rules & Alerts. Remove outdated rules when projects end, addresses change, or two rules begin doing the same thing.
If you use Outlook on more than one device, prefer rules configured in the mailbox settings when possible. Rules tied to a particular desktop installation may not behave the same way on the web or another device.

Troubleshooting

The rule does not run. Confirm it is enabled in the rules list, saved to the correct account, and positioned appropriately. Check that a test message really satisfies every condition and does not match an exception. A message that was already in the mailbox before the rule was created may need to be processed separately.

The message goes to the wrong place or gets an unexpected action. Open the rule and inspect its condition values, destination, exceptions, and order. Temporarily disable other overlapping rules and test again. In classic Outlook, a client-only rule may require Outlook to be running and connected to the account.

The rule cannot be saved or a feature is missing. Check whether your account type supports the chosen action and whether your organization has restricted it. For example, administrators may block automatic forwarding. Try the web or desktop rules editor for your account, update Outlook, or ask your Microsoft 365 administrator about policy restrictions. Outlook for Mac and some account types do not expose every rule action available in classic Outlook for Windows.

A rule works on one device but not another. Check whether it is a server-side mailbox rule or a client-only rule. Server-side rules are handled by the mail service and are generally more consistent across devices. A client-only rule may only run in classic Outlook for Windows while that app is open. If practical, recreate the rule in the mailbox’s web settings using a supported condition and action.

Frequently Asked Questions

Can I create a rule to move messages from one sender automatically?

Yes. Create a rule with a From condition for that sender and a Move to folder action. Select the exact sender address and destination folder, then send or wait for a matching message to confirm it works.

Do Outlook rules apply to messages already in my inbox?

Usually, a rule starts handling incoming messages after it is saved. Classic Outlook for Windows may offer an option to run a rule on existing messages in a selected folder. If that option is unavailable, move or sort older mail separately.

Can I use the same rules in new Outlook and classic Outlook?

Many mailbox rules work across Outlook versions, but the editors and available actions differ. A rule that depends on a classic desktop feature may not run in new Outlook or on the web. Check the rule list in the version you use most often.

Will a forwarding rule work when my computer is off?

A server-side forwarding rule can generally work without your computer running. A client-only rule may require classic Outlook to be open. Your Microsoft 365 administrator may also restrict automatic forwarding, particularly to addresses outside your organization.

How do I edit or delete an Outlook rule?

Return to Mail > Rules in new Outlook or Outlook on the web and select the rule to edit, or use its delete control. In classic Outlook for Windows, open Home > Rules > Manage Rules & Alerts, select the rule, and choose Change Rule or Delete. On Mac, return to Outlook > Settings > Rules.
