Enable Users to Easily Submit Junk, Phishing, and SPAM Messages in Outlook

Enable Users to Easily Submit Junk, Phishing, and SPAM Messages in Outlook

The email security analysis capabilities in Microsoft Office 365 are unmatched in the industry, offering subscribers the best protection available from email categories such as junk, SPAM, phishing, malicious, etc. But, from time to time a message will slip through that should have been classified as SPAM. If you are a Microsoft Managed Service Provider or a network administrator, the question becomes how do you enable your users to easily report these emails to the Office 365 analysis services?

I have written this blog to describe how you can publish an Outlook add-in (no cost) to the Outlook ribbon for users to simply highlight an email, classify it as Junk or phishing email, and then click to submit. It doesn’t get any easier than this! This seems to be a hidden gem that I want to create much more awareness about to our many Microsoft partners and Office 365 administrators. Below are instructions about how to install it on a user workstation to test with, how to administratively install it across all accounts in your Office 365 tenant, as well as how to then monitor for Junk and Phishing messages that have been submitted. While the intent of this article is to describe how to install and report unwanted emails, this Outlook Add-in also enables a user to report email that may have been incorrectly classified (Not Junk).

Although this blog is focused on the Outlook Add-in for reporting SPAM, other useful Add-ins should also be considered for installation such as Translator and Weather. There are hundreds of additional add-ins available for Outlook to review and choose from that may be perfect for your organization!

Additional information about how to submit SPAM, non-spam, and phishing scam messages for analysis are available in this TechNet Link.
