TL;DR
Outlook junk mail settings help filter out spam and unwanted emails by allowing you to block senders, create safe lists, and adjust filtering levels. Access these settings under Home > Junk > Junk E-mail Options in the Outlook desktop app or Settings > Mail > Junk email in Outlook Web. Fine-tuning these options prevents missing important emails and reduces clutter.
If you are tired of sorting through spam or finding important emails in your junk folder, it’s time to explore Outlook junk mail settings. Microsoft Outlook includes a built-in junk email filter that automatically identifies unwanted messages, but you can customize it for greater accuracy.
From creating safe sender lists to blocking specific addresses and domains, Outlook provides several options to help you take control of your inbox. By understanding and adjusting these settings, you’ll improve email productivity and reduce the chance of false positives.

Junk E-mail Options Explained
In the Junk E-mail Options dialog, you’ll find several tabs:
Options Tab
This tab controls the level of protection:

Choose the level based on your email habits and the frequency of spam.
Safe Senders Tab

Blocked Senders Tab

- Emails from these will go directly to your Junk folder
International Tab

How to Stop Emails from Going to Junk
Important emails sometimes end up in the Junk folder. Here’s how to fix it:
