Office 365 - Submit a message as spam

This document describes how users can help us improve campus junk mail filtering by reporting messages that were not flagged as spam. Doing this sends the feedback to the campus filtering engine and allows us to better identify spam in the future.

Important: Before you submit a message as spam, you should verify if the message is actually spam or graymail. To manage mail that is not spam, review the junk email and phishing and/or Clutter documentation.

To report a spam message that was not delivered to your Junk Email folder:

    • Use the "Report Spam" link (Recommended for Outlook on the web and all desktop versions of Outlook, except Outlook 2011/2010)
      • report spam link

        Using the "Report Spam" link helps to improve the spam filtering system used by UW-Madison so that similar messages won't be delivered to your inbox in the future. This feature is available in Outlook on the web, Outlook 2016/2013 for Windows, and Outlook 2016 for Mac only. Individuals using Outlook 2011 (Mac), Outlook 2010, or a non-Microsoft email client will need use the instructions under "Manually forward the message".

        Important: At this time, some users are unable to use the "Report Spam" function in certain Outlook desktop clients. If you are experiencing this issue, you can use Outlook on the web or manually forward the message (section below).

          1. Via Outlook on the web or desktop Outlook, open the the message you want to report as spam.
          2. Click the Report Spam link, located above the content of the email.

          3. You will be presented with a disclaimer. Once you have read the disclaimer, click the Report Spam button located below the disclaimer.


            • If you are using a computer with a smaller screen, the "Report Spam" button may be obscured from view. To work around this issue, double-click on the message to open it in a separate window, then maximize the window. This should allow for enough space for the "Report Spam" button to be displayed below the disclaimer.
          4. After a few seconds, the message will be processed and submitted to our system for analysis. It will also be moved to your "Junk Email" folder.

    • Manually forward the message (Recommended for Outlook 2011/2010 and non-Microsoft clients only)
      • If you are using Outlook 2011 (Mac), Outlook 2010, or any non-Microsoft email client (e.g., Thunderbird, Apple Mail, Android, iOS, etc.), you will not see the "Report Spam" link. However, it is still possible to report the message as spam, so that UW-Madison's spam filtering system can adjust to catch similar messages in the future.

        To report a message as spam, forward the message as an attachment to Note: you can attach more than one junk email when sending.

    • Create a Quick Step (Recommended for Outlook 2010)
      • If you are using Outlook 2010, create a Quick Step to report the message as spam. This process will send the message to our spam detection system and will be processed accordingly.
