Be an asset to your own security. In this article, learn how to report malicious emails in Outlook to keep junk and phishing emails away.

While there are many platforms for reporting malicious emails, our previous post dives deep on the email quarantine platform called Microsoft Defender ATP (Advanced Threat Protection). We recommend that you review all email quarantine options, but to report malicious emails in Outlook properly, Microsoft Defender ATP is an easy pick for many organizations since it is bundled with Microsoft 365 Exchange email services.   


Report Message Tool – Submissions 

By default, the reporting of junk email or phishing with the Report Message button in Outlook is sent over to “submissions” for Microsoft to analyze.  This process takes about a week for your team to view the “result” under the “report submissions” section. 


Quarantined Messages    

Future-related emails can be found under quarantine if the Microsoft analysis “result” deems so.  An alternative future can be found for “results” deems safe for future releases, meaning some user reported the message was “not junk”.  Read below to learn more about Quarantine and policies related to it.

The user can report messages that are not junk.  Be careful with this feature.  It is possible you are being duped into believing a malicious email is not junk.  Make sure you analyze before proceeding. 



How do I install the Report Message tool plugin? 

The Microsoft Defender ATP Report Message plugin is available through the Outlook “File” tab if it is not there by default. 

NOTE: You can go the same add-in location for alternative spam-filtering platforms if your organization is utilizing some other spam and phishing emails platform.  

Finally, there are options for your IT administrator to perform a mass deployment of the Microsoft Defender ATP plugin. Follow our “Centralized deployment Report Message/Phishing add-in post” for more details. 

If necessary, you can query “report message” in “Add-Ins for Outlook” in order to add the Report Message button in Outlook (the desktop version). 


Report Submission Process

How do I review the status from Microsoft for emails reported? 


What if you are those pesky junk emails keep coming? 

– In this case, please share the 2-3 Submission IDs with Microsoft Support and they will escalate the case to the next level team for further analysis.

What does “result” mean any the “report submissions” illustration below? 

– The final verdict is shown on the right side under “result”.  This means Microsoft took a week or so to analyze and returned with their final verdict as to how the email is processed.

What are the types of “results”? 

– If it’s classified as ‘Bulk’, then it has been reported to Microsoft and the same with the ‘Junk’ verdict for the emails too – such emails going forward should be blocked by the Spam filters. 

– The emails blocked due to user settings will keep getting blocked until the configuration/setting that is causing the issue is changed by the admin or mailbox owner.
