There are several steps you can try to fix Outlook junk email filter not working:
- Make sure that your Outlook's junk email filter is turned on. You can find this option under the "Home" tab and then "Junk" in Outlook.
- Check your "Blocked Senders" and "Safe Senders" lists to ensure that the email addresses or domains that you want to receive emails from are not accidentally blocked.
- If you're using Outlook in a corporate environment, check to see if your organization has a spam filter that may be blocking certain emails.
- Make sure that your Outlook is up to date, as updates may include bug fixes for the junk email filter.
- Try to run the Inbox Repair Tool (scanpst.exe) on your PST file to check for errors.
- Check that the email is not in the Clutter folder. Clutter is a feature of Office 365 that automatically categorizes low-priority email.
- If none of the above steps work, you may need to seek help from an our support.
It's important to keep in mind that the specific steps may vary depending on your setup and the version of Outlook you are using.
