How to Get Rid of Spam Emails in Outlook

Dealing with spam in Outlook can be frustrating, but a combination of built-in protections, smart filtering, and targeted add-ins can significantly reduce unwanted messages. This guide walks through practical steps to reclaim your inbox while keeping legitimate emails intact.

Quick Answer

Start by tightening Outlook’s built-in junk mail settings, enable focused inbox if available, and install a reputable spam or phishing protection tool. Regularly review junk mail, train the filter with legitimate messages, and consider complementary add-ins listed below to bolster defense against phishing and bulk mail.

What You’ll Need

Outlook spam filter add-in for Windows
Outlook email security software for Office 365
Phishing protection plug-in for Outlook
Default antivirus software and updated definitions
Stable internet connection and a current Outlook version

Before You Start

Before making changes, back up important emails and ensure you have administrative access if installing add-ins. Never share your passwords or security codes via email, and avoid clicking suspicious links. This process may take some time as filters learn from your email behavior. Typical setup and tuning can range from 15 minutes to an hour depending on your environment.

Step-By-Step: How To Get Rid Of Spam Emails In Outlook

Open Outlook and review the Junk Email Options. Set filtering to High and enable additional protections if available.
Enable Focused Inbox (if your account supports it) to separate likely important mail from less relevant items.
Mark a known spam email as Junk. Move it to Junk and choose to always block sender or domain to train the filter.
Review the Junk Email folder periodically. If legitimate mail lands there, right-click and mark as Not Junk to improve future delivery.
Install and configure a reputable Outlook spam filter add-in for Windows to supplement built-in protections.
Install Outlook email security software for Office 365 and enable real-time protection and phishing alerts.
Enable phishing protection plug-in for Outlook and customize the alert level and reporting options.
Use safe sender and block list to manage trusted contacts versus unknown senders.
Apply domain-based authentication checks where available (SPF, DKIM, DMARC) if your mail server supports it.
Review and adjust rules or filters for newsletters and transactional emails to maintain desired delivery.
Set up automatic rules to move newsletters to a specific folder, classified as optional reading, to keep the Inbox clean.
Regularly update all add-ins and Outlook to ensure compatibility with the latest security features.

Troubleshooting

Symptom	Likely Cause	Fix	Prevention
Legitimate emails go to Junk	Overly aggressive filters	Review Junk Mail options and mark messages as Not Junk	Train filters with similar legitimate emails

Buying Guide

When choosing tools to curb spam and phishing in Outlook, consider these factors to optimize protection without sacrificing productivity.

Size and compatibility: Ensure add-ins support your Outlook version (Windows, Office 365) and enterprise configuration.
Noise level vs. protection: Look for a balance between aggressive filtering and minimal false positives.
Energy efficiency and performance: Select lightweight add-ins that don’t slow down email performance.
Controls and customization: Prioritize tools that allow per-user or per-domain rules and easy whitelisting.
Placement and deployment: Consider whether the solution works client-side, server-side, or via your mail gateway.
Support and updates: Check vendor updates frequency and support availability.
Cost considerations: Evaluate total cost of ownership, including licensing and maintenance.

Would you benefit from a layered approach with multiple protections, or is a single, robust add-in enough for your needs? A combination often provides better coverage while keeping legitimate email accessible. Always test changes in a controlled group before organization-wide deployment to minimize disruption.
