Stop Junk Email in Outlook with Simple and Effective Methods

5/5 - (1 vote)

Regular Outlook users have definitely noticed how many unwanted emails are in their inboxes. Some are promotions, some are random newsletters you never signed up for, and some are just straight-up spam. It gets annoying fast, especially when important emails get lost in clutter. The good news is that there are a few simple ways that you can use to stop junk email in Outlook.

Why Junk Emails Keep Coming to Outlook?

Many users think spam emails are still appearing in their Outlook inboxes even after they stop receiving them.

  • Your email address may have been sold or shared by a website you signed up for.
  • The spammers use bots that randomly generate and test email addresses until they find active ones.
  • Clicking on a suspicious link even once can confirm to spammers that your email is active.
  • Data breaches from other platforms can expose your email to the wrong people.
  • Some senders keep emailing even after you ignore them because there’s no consequence. 

How Outlook Handles Junk Mail by Default

Microsoft Outlook has a built-in feature that helps to catch spam junk emails on its own. When it spots something suspicious, it moves it to the Junk Email folder automatically instead of dropping it in your main inbox.

But the default settings are very basic. It’s set to a low protection level out of the box, which means a lot of unwanted emails still move through without any problem.

It also doesn’t learn from your behavior on its own. So even if you keep deleting the same type of spam, Outlook won’t automatically start blocking it unless you tell it to. That’s why most people adjust things manually to block junk emails in Outlook. 

Simple Methods to Stop Junk Email in Outlook 

In this section, we will move on to some ways that will help you avoid those junk emails. Additionally, you don’t need to have any technical knowledge to block spam emails in Microsoft Outlook. 

Method 1: Use Outlook’s Built-in Junk Email Filter

Outlook has a junk filter already running in the background. Most people just don’t know you can make it stronger. Here’s how to adjust it:

  1. Open Outlook and click on the Home tab.
  2. Click Junk and then select Junk Email Options from the dropdown.
  3. You’ll see a few protection levels — Low, High, and Safe Lists Only.
  4. Switch it to High if you’re getting a lot of spam.
  5. Click Apply and then OK to save the changes.

Once you set it to High, Outlook will start catching more junk before it hits your inbox.

Method 2: Block a Specific Sender in Outlook

If the same person or company keeps emailing you, just block them directly. It takes about ten seconds.

  1. Right-click on the email from the sender you want to block.
  2. Hover over Junk in the menu.
  3. Click Block Sender.
  4. Outlook will move that email to junk and block any future emails from that address.

That sender won’t be able to land in your inbox again after this.

Method 3: Block Junk Emails in Outlook Using Safe/Blocked Senders List

This method lets you manage a whole list of blocked senders in one place instead of doing it one by one.

  1. Go to Home and click Junk.
  2. Select Junk Email Options.
  3. Click on the Blocked Senders tab.
  4. Hit Add and type in the email address or domain you want to block.
  5. Click OK to save.

You can also add trusted senders to the Safe Senders list here so their emails never go to junk by mistake.

Method 4: Stop Spam Emails in Outlook by Unsubscribing

Sometimes the easiest fix is just unsubscribing. If it’s a newsletter or promotional email, there’s usually an unsubscribe link at the very bottom.

  1. Open the spam or promotional email.
  2. Scroll to the bottom and look for an Unsubscribe link.
  3. Click it and follow the steps on the page.
  4. Give it a day or two, and those emails should stop.

Just be careful with this one. Only unsubscribe from emails that look like real companies. If the email looks shady, don’t click anything in it — just block the sender instead.

What Should You Do Now

These methods should help you to stop junk email in Outlook without trouble. Some of them take less than a minute to set up and make a noticeable difference quickly.

Before you start making changes to your Outlook settings or doing anything major with your mailbox, it’s actually a smart move to take a backup first. For that, you can use the Cigati PST Converter Tool. It lets you back up your Outlook PST files without any complicated setup. Your emails, attachments, and folder structure stay intact.

Once your backup is done, go ahead and apply whichever spam blocking method works for your situation. Most users find that combining two or three of these methods gives the best results.
