How to Create Rules in Outlook 365 to Organize Email

To create a rule in Outlook 365, open Settings > Mail > Rules in new Outlook or Outlook on the web, select Add new rule, set the conditions and actions, then save it. In classic Outlook for Windows, use Home > Rules > Manage Rules & Alerts. Rules can automatically sort, flag, forward, or otherwise handle messages as they arrive, so you spend less time managing your inbox.

The exact screens depend on which Outlook app you use. The instructions below cover new Outlook, Outlook on the web, and classic Outlook for Windows. Decide what should trigger the rule and what Outlook should do before you start. For example, you might move messages from a particular sender into a project folder.

What You’ll Need

An Outlook 365 account and access to its mailbox.
A clear condition, such as a sender address, a word in the subject, or a recipient address.
A destination folder if you plan to move messages. Create one first if needed: right-click your mailbox or a folder and choose New Folder in new Outlook, or use Folder > New Folder in classic Outlook for Windows.
Optional: a sample message to help identify the exact sender, subject wording, or other detail the rule should match.

Step-by-Step

Choose the Outlook version you are using. In a browser, open Outlook on the web and sign in to your Microsoft 365 account. In the Windows app, look for a New Outlook switch or label. If you are using the newer interface, follow the new Outlook route below; if you are using the traditional ribbon and desktop layout, follow the classic Outlook route. The menus differ, but the purpose of the settings is the same.
Open the rules page in new Outlook or Outlook on the web. Select the gear-shaped Settings button near the top of the window. Choose Mail, then Rules. Select Add new rule. If you do not see the option right away, expand the Mail settings or use the Settings search box to look for Rules. In Outlook for Mac, the current interface may show rules under Outlook > Settings > Mail > Rules; in some classic Mac layouts, use Tools > Rules. Menu labels can vary slightly by release.
Name the rule so its purpose is easy to recognize. Enter a short, descriptive name, such as “Move weekly sales reports” or “Flag messages from Jordan.” A useful name matters if you later need to edit, disable, or reorder several rules. Avoid names such as “Rule 1,” which do not explain what the rule does.
Choose one or more conditions. Select the circumstances that identify messages to handle. Depending on the Outlook interface, conditions may include who sent the message, words in the subject, words in the message body, importance, or whether your address is in the To or Cc line. Add only conditions that describe the messages you actually want. If you choose both a sender and a subject condition, Outlook generally requires a message to meet both conditions; it will not treat them as alternatives unless the interface provides an explicit choice.
Select the action. Common actions include moving a message to a folder, marking it as read, flagging it, assigning importance, or forwarding it. Choose Move to when you want incoming mail filed away, then select the destination folder. Check the selected folder carefully; similarly named folders can make it easy to send messages to the wrong place. Some actions and options vary by account type and Outlook version.
Add exceptions if necessary. An exception prevents the rule from applying to certain messages even when they meet its conditions. For example, a rule that moves routine messages from a supplier could exclude messages with “urgent” in the subject. Use exceptions sparingly: a complicated set of conditions and exclusions can make a rule difficult to understand and troubleshoot. Review the full summary before saving.
Choose whether to run the rule on existing messages. New Outlook and Outlook on the web may offer an option to apply a rule to messages already in the folder. Select it only if you intend to process existing mail as well as future messages. If the option is not present, the rule may apply only to incoming messages. For a one-time cleanup, consider moving messages using search and selection instead of changing how future mail is handled.
Save, then verify the rule. Select Save or Finish, depending on the version. Return to the Rules page and check that the rule is enabled and that its name, conditions, action, and exceptions are correct. Send yourself a test message that meets the conditions, or wait for a suitable incoming message. Check the destination folder and confirm that messages that do not meet the conditions remain unaffected.
In classic Outlook for Windows, create the rule through the ribbon. Select the Home tab, choose Rules, then Manage Rules & Alerts. Select New Rule. You can start from a template, such as moving messages from a specific sender, or choose Apply rule on messages I receive to build a rule from scratch. Select Next, check the conditions, and select the underlined values in the lower part of the wizard to specify a sender, phrase, or folder.
Finish the classic Outlook wizard and test it. Select Next to choose actions, then add any exceptions on the following screen. Give the rule a name, check Turn on this rule, and, if offered, select Run this rule now on messages already in Inbox only when that is intended. Select Finish, then Apply and OK in the Rules and Alerts window. Send or locate a matching message to confirm that the rule behaves as expected.

Rules created in Outlook on the web or new Outlook are commonly processed by the mail server, so they can keep working when the desktop app is closed. Some classic Outlook rules depend on Outlook running on the computer. The classic wizard identifies many of these as “client-only.” This can happen when an action needs access to a local file or a feature that is available only in the desktop app. Check the rule details if it does not run while Outlook is closed.

Common Mistakes

Making the conditions too broad. A rule based on a common word such as “report” may catch unrelated messages. Use a distinctive sender, complete address, or more specific subject phrase where possible.
Assuming multiple conditions work as alternatives. Conditions are often combined so a message must satisfy all selected conditions. Read the rule summary and test a message that should match before relying on it.
Choosing the wrong folder or action. A move action can make messages seem to disappear from the Inbox. Confirm the destination folder and check it after testing.
Creating overlapping rules without checking their order. One rule might move a message before another rule can act on it. In classic Outlook, review the order in Rules and Alerts. In new Outlook or web, check the rules list and any option to stop processing additional rules.
Expecting a rule to fix old mail automatically. Unless you choose an available run-on-existing-messages option, a rule generally handles new incoming messages only. Existing messages may need to be processed separately.
Forgetting exceptions or leaving a rule disabled. An unintended exception can exclude messages, while a disabled rule will not run at all. Check both before deciding that Outlook is malfunctioning.

Tips

Start with one simple condition and one action. Add complexity only after the basic rule works.
Use a dedicated folder for a category of messages instead of moving mail into an existing folder whose purpose is different. A clear folder structure makes automated filing easier to review.
Test with a message that closely resembles the mail you expect to receive. If you use a subject condition, check whether the text is likely to appear in replies or unrelated messages too.
Keep important messages visible. Instead of moving every message from a person, consider flagging or categorizing them, or add an exception for urgent subjects.
Review rules periodically. When a project ends, a sender changes addresses, or a folder is no longer used, update or remove the rule so messages do not keep going somewhere unexpected.
Use names that describe both the match and the action, such as “Vendor invoices to Finance folder.” This is especially helpful when reviewing a long list of rules.

Troubleshooting

The rule does not appear to run. Confirm that it is enabled, saved, and attached to the mailbox where the message arrived. Check whether the message really meets every condition and whether an exception excludes it. Test with a new message, since rules may not automatically process older mail. If it is a client-only classic Outlook rule, leave Outlook open and connected to the account.

Messages go to the wrong folder. Open the rule and inspect its destination, then verify that another rule is not moving the same messages afterward. Look at the rules list for overlapping conditions and check their order. Temporarily disable unrelated rules and test again, then re-enable them one at a time to identify a conflict.

The rule catches too many or too few messages. Refine the conditions. Replace a general word with a more distinctive phrase, use the exact sender address when appropriate, or remove a condition that is unnecessarily restrictive. Check how Outlook treats the chosen condition and whether it searches the subject, body, or both. Test both a message that should match and one that should not.

You cannot find Rules or cannot save a change. Check that you are signed in to the correct Microsoft 365 account and that the mailbox has finished loading. Try Settings search for “Rules,” refresh Outlook on the web, or reopen the desktop app. In a work or school account, an administrator may restrict certain features or mail flow. Contact your Microsoft 365 administrator if the option is unavailable or an error refers to organization policy.

A rule works on the web but not as expected in classic Outlook, or the reverse. Compare the rules in the same mailbox and check for client-only actions, conflicting rules, or a rule that exists in a different account. Server-side rules can run without Outlook open; client-only rules require the desktop app to be running and connected. If a rule is damaged or its behavior remains unclear, disable it, recreate a simpler version, and test before deleting the original.

Frequently Asked Questions

Do Outlook rules work when my computer is off?
Server-side rules generally run in your mailbox even when your computer is off. A client-only rule in classic Outlook requires the desktop app to be running and connected. The action and conditions determine which kind of rule Outlook creates.

Can I apply a new rule to messages already in my Inbox?
Sometimes. The rule setup may include an option to run it on existing messages. If you do not see that choice, use search and move or flag the matching messages manually, or check the rule-management options in your Outlook version.

Can a rule forward messages to another person?
Some Outlook versions let you choose a forward action. Your organization may restrict automatic forwarding, especially to addresses outside the company. If forwarding is unavailable or messages do not arrive, check with your Microsoft 365 administrator.

Can I create the same rule on a Mac?
Yes. Outlook for Mac includes rules, although the menu path depends on whether you use the newer or classic interface. Look under Outlook settings for Mail and Rules in the newer interface, or under Tools and Rules in some classic layouts. Outlook on the web is another option for mailbox rules.

How do I edit, disable, or delete a rule?
Open the Rules settings page in new Outlook or web, select the rule to edit, or switch it off or remove it. In classic Outlook for Windows, go to Home > Rules > Manage Rules & Alerts, select the rule, and choose the available change or delete option. Save or apply the change before closing.

Why did a rule move a message but not mark it as read?
Another rule may have acted first, or a stop-processing option may have prevented later rules from running. Review the order, actions, and rule summary. If both actions matter, where supported, put them together in one rule and test again.
