The spam filter in Outlook is not perfect and new forms of junk mail show up every day. To help Microsoft Exchange Online Protection improve and adapt the Outlook spam filter for continuing effectiveness, you can report any spam it misses.

Instructions in this article apply to Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, and Outlook for Office 365.

Check That You've Enabled the Spam Reporting Tool

First, make sure the Junk E-mail Reporting Tool for Microsoft Office Outlook is installed. If the Report Junk or Report Phishing option is missing from the Junk menu, you can enable the add-in.

  1. Go to the File tab.
