How Do I Stop Outlook.com from Putting Legitimate Messages in the Junk Mail Folder?

When it tries too hard to protect you.

Outlook.com, like most email services, tries hard to keep spam out of your inbox. Sometimes it gets a little too aggressive. I'll look at how to tame it.

Question: My outlook.com is putting legitimate emails into its junk mail folder. I never see the emails because outlook.com is putting them in junk mail. It seems very random, but some of my closest friend’s emails are going into the junk folder, as well as other legitimate contacts. Can I just not use outlook.com — do I need it? How do I stop the filtering of legitimate emails into the outlook.com junk folder?

Spam is a big problem, and email providers go to great lengths to filter it out. Microsoft is no different; I’m sure their email infrastructure deals with an incredible amount of spam.

With any of Microsoft’s email addresses — @live.com, @hotmail.com, @outlook.com, and others — even if you use a desktop email program, you’re still using Outlook.com whether or not you visit it on the web.

Let’s look at the options you have to make sure you get the email you want.

TL;DR:

Taming Outlook.com's spam filter

Outlook.com aggressively filters spam, sometimes mislabeling legitimate emails. You can’t turn off the junk filter, but you can train it by marking legitimate emails as “not junk” and adding trusted contacts to the Safe Senders list. Regularly check your junk folder to ensure important emails aren’t missed.

Junk = Spam

Junk and spam are the same thing. Microsoft uses the term junk whereas the rest of the world uses the term spam.

Turn off Outlook.com’s junk mail filter?

You can’t.

Unfortunately, there isn’t currently an option to turn off Outlook.com’s spam filter.

In the past, I listed tricks you might play with Outlook.com’s filters, but those tricks no longer work. Today, spam filtering is not optional, and it happens before any rules are processed.

As a result, we have only partial, imperfect solutions.

Train the Outlook.com junk mail filter

The preferred solution is to leave the junk mail filter enabled and train it instead.

If you’re using a desktop email program to access your Outlook.com account, that means you periodically need to log in to Outlook.com on the web.

Mark junk as junk

If you find junk in your Inbox, right-click on the message, click on Report, and then click on Report junk.

I don’t believe there’ any advantage to “Report phishing” or “Report a concern”. I report all spam as junk.

This will:

  • Train the spam spam filter on what looks like junk to you.
  • Block the sender of the message.1
  • Move the message to the junk folder.

Mark legitimate email as not junk

Periodically review your Junk Email folder. If you find a message that should not be filtered as junk, right-click on the message, click on Report, and click on Not junk.

This will:

  • Train the spam spam filter on what it should not consider junk.
  • Give you the option to add the sender to the “Safe Senders” list. Once there, email from that sender will not be filtered for spam.
  • Move the message to the Inbox.

All this is to “train” Outlook.com’s spam filter. Unfortunately, your input that something is or is not junk is just one of several signals that the junk mail filter uses, and you may need to repeat this more than once as new messages arrive… sometimes many more times.

Set up Safe Senders

If an email address is on the Safe Senders list, Outlook doesn’t filter it for junk. Adding your friends to this list should ensure that their emails to you do not end up in the junk folder.

Click on the gear icon in the upper right corner, make sure Mail is selected on the left, and click on Junk email in the middle column. Scroll down until you find the “Senders” section.

You can add two different types of entries.

  • Individual email addresses. Any email from that address will bypass the junk mail filter.
  • Entire domains. Any email from an address on that domain will bypass the junk mail filter.

Do this

Unfortunately, Outlook.com’s spam filter has a fairly poor reputation and fewer controls than we would like. But it’s all we have. Learning to use it appropriately will hopefully improve your experience overall.

  1. The problem I am having is that Outlook is ignoring the safe senders list. Both the sender and its domain are explicitly listed in the safe senders list, yet off the the Junk folder they go.

    Good luck getting a hold of someone at Microsoft. You get what you pay for.

  2. Though I have a rule set up for directing emails from a certain sender to go to a particular folder (and the rule was working just fine till a couple of days ago), now the emails are being sent to the junk folder.

    So SPAM protection occurs before the rule is processed?

      • Given that the article’s on Outlook.com that was my assumption. And indeed, making sure to mark as “Not Junk” would be one thing to do, but I would expect the rules to process before spam detection, but that appears not to be happenig for you. I’d also make sure to add the email address to the allow list.

  3. I just tried the suggested solution for emails disappearing without cause and tried the suggestion to create with and without attachment rules.
    There is no longer an option to choose “without”, however, there now appears there is an option”Apply to all messages”, with the action “Send to Inbox” available.
    I’m trying this for now, but if it works the way I want it, then it may be time for an update on this post
    Keep up the great work
