Issues with Microsoft Outlook filters and antispam

Updated on February 21st, 2023

Spam filters in Outlook should be on guard clockwork while you keep polishing and training them on your end by marking junk email messages sneaking into your inbox as spam. However, you still could see an email or two (or more) in a place where they shouldn't be.

In February 2023, as Bleeping Computer notes, numerous Outlook users (users of and associated MS-hosted free accounts and/or hosted domains) reported that their inboxes were literally drowning in the ocean of spam emails because spam email filters turned out to be broken. It means that all messages previously tagged as spam start landing back in your inboxes mixing with the important ones.

If you have faced the issue mentioned, we recommend you try Screener from Clean Email, which is completely free within two weeks. When Screener is enabled, Clean Email intercepts all emails from new senders and keeps them quarantined for your review instead of delivering them to your inbox. You can review all quarantined messages in a separate section and decide whether to accept the senders’ messages or block the senders.

If you are an Outlook (,, etc.) user and you crave to stop spam dead in its tracks by keeping messages from first-time senders out of your Inbox—sign up to Clean Email with your account and enable a 14-day trial (no credit card is required). Read more about Screener and how it can help you to get rid of unwanted senders.

How To Find Junk Mail In Outlook And Empty It

Outlook Junk Mail settings check all incoming messages automatically and look for signs of spam. If you receive a message that Outlook has determined is malicious or unwanted, it will sort emails in Outlook to place the undesired messages in the junk email folder instead of your primary inbox.

It doesn’t delete these messages though, and sometimes the Outlook spam filter places something in the junk email folder by mistake, so you need to know how to find and delete junk mail in Outlook.

6 Additional Tips on How to Stop Junk Email in Outlook

There are currently close to four billion email users worldwide. Unfortunately, this means there are lots of spam messages being sent and received each and every day. Unless you learn how to stop spam emails from winding up in your Outlook inbox, you can expect your mailbox to eventually be so full of useless messages that make using it nearly impossible.

The good news is that learning how to get rid of spam doesn’t require much effort, and it certainly doesn’t require any expert knowledge. All you have to do is familiarize yourself with six simple email management tips and use Clean Email in addition to the Outlook spam filter.

1. Don’t Respond to Spam

Never respond to spam messages. Ever. It may seem obvious, but you would be surprised how many people break this simple rule and open unsolicited emails. Sometimes, they even download attachments, which is how most malware infections begin.

The trick is to learn how to separate legitimate messages from illegitimate ones. If you don’t recognize the sender's address, you’re most likely dealing with an unsolicited email from a clever spammer who has managed to circumvent the Outlook spam filter. Look at the subject line and think hard if it makes sense and doesn’t contain grammar mistakes.

Spammers often make outrageous claims and write emails that are full of spelling errors and grammar mistakes. Legitimate senders, on the other hand, take time to proofread their emails to make a good first impression. It’s also very rare for legitimate senders to send emails with attachments without first touching base.

2. Don’t Share Your Email Address

Do you know how an email spammer gets your address in the first place? They usually find it posted online! We understand that it can be tricky, especially if you have a website or maintain an active online presence but try not to publish your email address online. If you absolutely must share it with others, at least disguise it by substituting the @ symbol with the word “at.” This won’t fool all email address scrapers used by spammers, but it will throw off a good percentage of them.

When you do give your email address to someone else, pay attention to your inbox and monitor the number of spam emails you receive. A major uptick in the frequency of spam emails could mean that the person with whom you’ve shared your address has published it somewhere. When registering on websites, consider using a disposable email address instead of your real one. There are many services that let you create as many disposable email addresses as you want, and most of them are free.

3. Report Junk Emails

The sad truth is that the Outlook junk email filter leaves a lot to be desired. You can, however, train it by reporting junk emails. When you mark a message as spam, it will not only disappear from your inbox but also appear on Outlook’s junk email filter. Next time the same sender attempts to send you a similar spam message, there’s a very high chance that the email will be detected and stopped from ever reaching your inbox.

How to Mark Emails as Spam in Outlook

You can filter spam in Outlook by following these directions:

  1. Go to to access your Outlook inbox on the web.
  2. Select the spam message or messages you’d like to filter out of your inbox.
  3. At the top of the screen, select Report. Then choose Report junk.
Select the Report junk optionSelect the Report junk option

4. Unsubscribe from Promotional Emails

Promotional emails are the curse of our modern era. However, most promotional emails today contain an unsubscribe link somewhere at the bottom of the message. All you have to do to unsubscribe is click on it.

Unfortunately, there are times when this Unsubscribe button isn’t easy to spot or available at all. Luckily, you can navigate to Settings → Mail → Subscriptions through Outlook to remove yourself from certain subscription lists directly through your email client. This is just one way you can learn how to stop spam emails in Outlook.

Check out your Outlook subscriptions

Additionally, you can check out our complete guide on how to unsubscribe from emails on Outlook.

Furthermore, you can use Clean Email to stop promotional emails from cluttering your mailbox, and it just requires a few clicks. This is because Clean Email is a bulk email organizer that analyzes your inbox and allows you to unsubscribe from unwanted messages with the click of a button, and it’s just as easy to delete or archive hundreds or even thousands of spam messages.

In fact, you can stop all newsletters forever or pause them all at once place, even if there is no obligatory Unsubscribe link in the email. It’s very handy, especially if you have limited time to dedicate to blocking spam on Outlook.

To stop junk email in Outlook using Clean Email’s Unsubscriber feature, simply:

  1. Go to:
  2. Sign in with your mail login and password.
  3. Select Unsubscriber from the left pane.
  4. Go through the list of active subscriptions and click the Unsubscribe option next to each subscription you no longer wish to receive (or select multiple of them and unsubscribe from them all with one click).

5. Get a New Email Address

Getting a new address just to stop junk email may seem like a drastic option, but we recommend it to everyone who’s losing the fight with spammers. Outlook lets you create as many new addresses as you need for free, and you might even be able to snatch a good username if you don’t wait too long. At the very least we recommend you create another email address just for online registrations and various other activities that might lead to junk infiltrating your inbox.

6. Use Temporary Email Services

If you’re not keen on managing another inbox just to stop spam emails from infiltrating your Outlook account, you have another option: a temporary email address.

A temporary account looks and works just like a regular email address except that it’s not meant to be used long-term. Most temporary addresses expire after anywhere from 10 minutes to a couple of hours, so using them for regular communication is not advisable.

Instead, we recommend you use a temporary email address as a way how to stop spam emails in Outlook from various websites that force you to create a user account. Here are a few reputable providers of temporary email services that you can choose from:

Besides temporary email services, you should also learn how to stop receiving junk email in Outlook with burner emails extension like Burner Mail for Chrome. Browser extensions are convenient to use because they are always just one click away, and they offer various useful extra features, such as real-time email notifications.
