Corrupted or outdated rules
Conflicts between multiple rules

How to Fix Outlook Rules That Aren’t Running Automatically

When Outlook rules stop working, it can disrupt your entire email workflow causing important messages to get lost in the chaos of your inbox. Whether your rules aren’t running automatically or simply not performing as expected, the steps below will guide you through diagnosing and fixing the issue.

Here are the most effective troubleshooting steps to fix Outlook rules that aren’t working:

1. Verify That the Rules Are Enabled

Start with the basics. A rule won’t work if it’s disabled.

Go to Home > Rules > Manage Rules & Alerts.
Ensure the checkbox next to each rule you want to use is selected.
Click Apply, then OK.

2. Check If It’s a Client-Only Rule

Some rules only function when Outlook is running on your computer. These are known as client-only rules.

Client-only rules won’t run on the server or in Outlook Web.
If you need a rule to run whether Outlook is open or not, create it as a server-side rule.

3. Test the Rule Manually

You can force a rule to run to see if it’s working:

Go to Rules > Manage Rules & Alerts.
Select the rule and click Run Rules Now.
Choose a folder and click Run Now.

If the rule works manually but not automatically, the issue may be with how or when it’s triggered.

4. Check the Rule Conditions

Misconfigured rule conditions can prevent the rule from executing properly.

Review filters such as “specific words,” “from people or group,” or “with attachments.”
Make sure there are no overly restrictive or conflicting criteria.

5. Recreate the Rule

If a rule is corrupted, it might not work even if everything looks right.

Delete the faulty rule.
Recreate it from scratch.
Avoid copying older rules or duplicating them if issues persist.

6. Reduce Rule Complexity

Outlook has a limit (typically 64 KB for Exchange mailboxes) on the total size of all rules.

Simplify overly complex rules.
Merge similar rules to reduce the total number.
Delete outdated or unnecessary rules.

7. Repair or Rebuild Your Outlook Profile

Corrupt Outlook profiles are a common cause of rule failures.

To create a new profile:

Open Control Panel > Mail > Show Profiles.
Click Add, create a new profile, and set it as default.

8. Force Quit and Relaunch Outlook for Mac

If you have moved to a legacy version of Outlook, the client rules need to be fixed. Therefore, the user can try to force quit and relaunch the application.

Select Force Quit from the Apple logo.
After choosing Outlook, click Force Quit.
To confirm your choice, tap the Quit again.
After a few minutes of waiting, launch the Outlook for Mac application once more.
