Mark a Message as Junk in Outlook

Train Outlook.com to spot the junk

The chances are good that Outlook.com filters most of the spam that is headed to your inbox to the Junk Email folder. However, some spam or other types of junk email inevitably makes it to your Outlook.com inbox occasionally.

You can delete that unwanted message, of course. You can also move it to the Junk Folder, which trains Outlook.com to identify similar junk emails in the future so that you don't see them in your inbox.

Move a Message to Junk Mail Folder in Outlook.com

To tell Outlook.com that a particular message made it past the junk mail filter, move it to the Junk Email folder.

  1. Go to Outlook.com in a browser and log in to your account.
  2. Open the junk message or check it in the Outlook.com message list. You can check more than one message to flag them all as spam at the same time.
  3. Click Junk in the toolbar at the top of the screen.
  4. Select the downward-facing More actions arrow at the top of the email and select Mark as junk from the options. You can also pull up the Mark as junk screen by right-clicking on the message.

When you move an email to the Junk Email folder, Outlook.com learns about the types of messages you consider to be junk.

The items in the Junk Email folder are deleted after 30 days.

Using Junk Email Filters

After a while, if you find that Outlook.com is enthusiastically moving emails that are not junk to the Junk Email folder, you can place the senders on a Safe senders list or Safe mailing list.

  1. Click the settings gear at the top of the mail screen.
  2. Select View all Outlook settings at the bottom of the Quick Settings menu that opens.
  3. Click Mail > Junk Mail in the Settings sidebar.
  4. Add the email address of a sender or domain that you want to receive an email from to the Safe senders list. If the email you want to receive comes in from a mailing list, the email may be snagged as junk because your email address does not appear in the To line. Add the address of the list if you trust it in the Safe mailing lists section.
  5. Click or press Save at the top of the screen.

Similarly, if Outlook doesn't recognize a junk mail sender, even after you've reported it by moving the email to the Junk Email folder, you can manually place the sender or domain on a Junk Email list.

  1. Click the settings gear at the top of the Outlook.com mail screen.
  2. Select View all Outlook settings at the bottom of the Quick Settings menu that opens.
  3. Click Mail > Junk Mail in the Settings sidebar.
  4. Add the email address of a sender or domain to either the Blocked senders or Blocked domains list to prevent any mail from them appearing in your inbox.
  5. Click or press Save at the top of the screen.
