How to Create Email Rules in Outlook 365

To create an email rule in Outlook 365, open Settings, go to Mail > Rules, choose Add new rule, set a condition and an action, then save it. Rules can automatically sort, move, flag, or forward messages as they arrive. The exact menu depends on whether you use new Outlook, Outlook on the web, or classic Outlook for Windows, so follow the matching steps below.

What You’ll Need

An Outlook 365 account and access to the mailbox where you want the rule to run.
A clear idea of which messages the rule should catch, such as mail from a particular sender or messages with a phrase in the subject.
If the rule will move mail, the destination folder should already exist, or you should be ready to create it while setting up the rule.
Permission to change mailbox rules. A work or school administrator may restrict forwarding or other rule actions.

Step-by-Step

Choose the Outlook version you are using. In Outlook on the web, open Outlook in your browser. In new Outlook for Windows, open the app and select the Settings gear near the top right. The rule settings are similar in these two versions. In classic Outlook for Windows, use the separate Rules & Alerts wizard described in step 7. If you are unsure which Windows app you have, look for a New Outlook switch in the app; classic Outlook has the traditional File tab and a fuller desktop ribbon.
Open the Rules page in new Outlook or Outlook on the web. Select the Settings gear, then choose Mail > Rules. If the Settings pane opens in a compact view, use View all Outlook settings if it appears, and then select Mail > Rules. Choose Add new rule. The settings page may look slightly different after Microsoft updates Outlook, but Mail and Rules are the locations to look for.
Name the rule so you can recognize its purpose. Enter a short, descriptive name, such as Move receipts to Finance or Flag messages from Jordan. A useful name makes it easier to find and edit the rule later, especially if you create several. Avoid names such as Rule 1, which do not tell you what the rule does.
Choose a condition that identifies the messages. Select a condition from the menu, such as From, Subject includes, or To. Then enter or select the sender, phrase, or address requested by Outlook. For example, a From condition can target one sender, while Subject includes can identify a recurring report by a distinctive subject phrase. Use the narrowest reliable condition: a phrase such as Monthly sales report is usually safer than the broad word report.
Add more conditions only when the message must meet all of them. If the rule builder lets you add another condition, use it to make the match more specific. For example, combine a sender condition with a subject phrase to catch only that sender’s invoices. Outlook generally treats conditions in one rule as requirements that must all match. If the interface offers a condition that covers several recipients or phrases, read its wording carefully; do not assume that adding another condition means either condition can match.
Choose what Outlook should do with a match. Select an action such as Move to, Categorize, Flag, Mark as read, or Forward to, depending on the options shown for your account. Choose the destination folder or category when prompted. To move project updates, for example, choose Move to and select the project folder. If you forward messages, check the recipient carefully and remember that your organization may block automatic forwarding outside the company.
Set exceptions and rule order thoughtfully. If available, add an exception for messages that should not be affected, such as mail marked with high importance or messages from a particular person. Review any option such as Stop processing more rules. Turning it on can prevent later rules from acting on the same message, which is useful when the first rule should take priority. If two rules can match one message, their order and actions can affect the result. Save a specific rule above a broad one when the settings page lets you reorder rules.
Save the rule and decide whether to apply it to existing messages. Select Save or the equivalent button. Some Outlook versions offer an option to run the rule now on messages already in the folder; enable it only if you want a one-time pass over existing mail. If that option is not shown, the rule normally applies to qualifying messages received after it is created. Check the rule list to confirm that the rule is enabled.
For classic Outlook for Windows, create the rule in the wizard. Select Home > Rules > Manage Rules & Alerts, then choose New Rule. To start with a blank rule for incoming messages, select Apply rule on messages I receive and choose Next. Check one or more conditions and select the underlined values in the lower pane to set the sender, words, or other details. Choose Next, select the action, and set its details. Add exceptions if needed, choose Next, give the rule a name, and select Finish. If offered, check Run this rule now on messages already in Inbox to process current messages. Select Apply, then OK.
Verify the result with a new test message. Send or wait for a message that meets the condition, then check the destination folder, category, or other selected outcome. Test with a message that should match and, if possible, one that should not match. This helps reveal a condition that is too broad, a misspelled subject phrase, or a rule-order conflict before you rely on the automation.

On Mac: Outlook for Mac also supports rules, but its layout can vary with the Outlook version. In current Outlook for Mac, open Outlook > Settings and look for Rules under Mail. In legacy Outlook for Mac, the Rules controls may be under Tools > Rules. Create the condition and action, then save. If you cannot find a particular action, check the web version or your organization’s help guidance; available rule options can differ by account type and app.

Common Mistakes

Using a condition that is too general. A rule for any message containing the word update may catch newsletters, automatic notices, and unrelated conversations. Prefer an exact sender, a distinctive subject phrase, or a combination that identifies the intended mail.
Choosing the wrong folder or address. Before saving, verify the selected destination folder and any forwarding recipient. Similar folder names make it easy to send mail somewhere unexpected.
Expecting a new rule to reorganize old messages automatically. Most rules handle incoming mail from the time they are enabled. Use a run-now option if available, or move existing messages separately.
Forgetting the rule order. A broad rule that moves a message first can make a later rule appear not to work. Check the order and whether Stop processing more rules is enabled.
Assuming rules override junk filtering or security controls. Outlook or your organization may handle suspected junk, quarantine, or external forwarding separately. A rule may not act on messages that never reach the mailbox or on actions blocked by policy.

Tips

Start with one simple action. First create a rule that moves a specific sender’s mail to a folder. Once you confirm it works, add categories, exceptions, or additional conditions if needed.
Create folders before building a group of rules. A tidy folder structure makes destinations easier to select and reduces the chance of choosing a similarly named folder. Keep important mail easy to find; do not route everything out of the Inbox without a plan.
Use categories when you want to keep mail visible. Moving a message removes it from its current folder, while categorizing it can make it easier to identify without changing where it is stored. This is useful for messages that still need a reply.
Review rules after changing your workflow. A rule for a former project, sender, or reporting process can keep sorting messages in a way you no longer expect. Visit Mail > Rules periodically, disable rules you no longer need, and edit outdated destinations.
Keep the condition and action understandable. A rule should be easy to explain in one sentence: when a message meets this condition, Outlook does this. If the rule has many exceptions or overlapping conditions, split it into smaller rules and test each one.

Troubleshooting

The rule does not appear to run. Confirm it is enabled and saved, then check that a new message really meets every condition. Compare the sender address and subject text with the rule, and make sure you are checking the correct mailbox and folder. A message already in the Inbox may not be affected unless you ran the rule on existing mail.

The message goes to the wrong place or gets changed twice. Look for another rule with overlapping conditions. Reorder the rules if possible, narrow the condition, or use Stop processing more rules when an earlier action should be final. Temporarily disable other likely rules and test again to identify which one is responsible.

A forwarding rule will not save or does not deliver. Check the destination address, then send a normal test message to confirm it is valid. Work and school accounts can block automatic forwarding for security reasons, and external forwarding may be disabled by an administrator. Ask your Microsoft 365 administrator to confirm the policy rather than trying to bypass it.

The menu or action is missing. Check whether you are in new Outlook, classic Outlook, Outlook for Mac, or the web app, because features and labels can differ. Update the app if appropriate, try Outlook on the web, and confirm the account supports the desired action. Some desktop-only or client-side actions require classic Outlook to be running; server-side rules can run without the desktop app when the account and action support them.

Messages are being treated as junk instead. Check the Junk Email folder and any quarantine or security portal your organization uses. A mailbox rule generally cannot process a message that has been blocked or diverted before it reaches the mailbox. If a legitimate sender is repeatedly filtered, use the organization’s approved safe-sender or reporting process.

Frequently Asked Questions

Do Outlook rules apply to messages already in my Inbox?

Usually, a rule affects messages that arrive after you create and enable it. Some versions provide a Run rule now option for existing messages. If you do not see that option, move or categorize the older messages yourself, or use classic Outlook’s wizard when it offers the run-on-existing-messages checkbox.

Can I create a rule from an email I have received?

Often, yes. In Outlook on the web or new Outlook, select or right-click a message and look for Rules or Create rule. Outlook can use details from that message to start the condition. Review every condition and action before saving; a rule based on one message may be broader or narrower than you intend.

Will a rule run when Outlook is closed?

Many rules for Microsoft 365 or Exchange mailboxes run on the mail server, so Outlook does not need to be open. Some actions or rules that depend on the desktop app are client-side and may require classic Outlook to be running. If a rule works only while the app is open, check its action and account compatibility.

Can one rule have more than one condition or action?

Yes, many Outlook rule builders let you combine conditions, add more than one action, and set exceptions. Conditions usually make the match more specific, so adding a second requirement can reduce the number of messages caught. Check the rule summary before saving to confirm it describes the intended logic.

Can I edit or delete a rule later?

Yes. Open Settings > Mail > Rules in new Outlook or Outlook on the web, or Home > Rules > Manage Rules & Alerts in classic Outlook for Windows. Select the rule to edit, disable, reorder, or delete it. If you remove a rule, messages already moved or forwarded are not automatically returned or recalled.
