No one likes spam or junk email.

The Outlook Junk Email Filter doesn’t stop delivery of junk email messages, but does the next best thing—it moves suspected spam to the Junk Email folder. Outlook's Junk Filtering system works with all SUMail accounts and can sometimes cause unintended emails to appear in the Junk Filter.

The steps below will show you how you can tailor your Junk Email Filter to work the best for you.

Report junk and phishing messages

For messages in the Inbox or any other email folder except Junk Email, use the following method to report spam and phishing messages directly from

  1. Select the junk, phishing, or spam email. Select the  Junk icon with the drop down arrow in the toolbar at the top of the Outlook on the web page .

  2. You will be presented with three options. Junk, Report Phishing, and Block Sender. Depending on the type of email you are reporting, it will send a report to Microsoft to help improve filtering in the future.

    If you mark an email as Junk or Phishing, the email will automatically be moved to the Junk Email folder in Outlook. If you choose to Block the sender, you will no longer receive email from that particular email account regardless of email type.

What's Junk email?

Junk email messages are typically referred to as spam. These are messages that you don't want to receive that may be advertising products you don't use or find offensive. If you choose the  Junk  option, a copy of the message may be sent to Microsoft to help update our spam filters, and the message will be moved from your Inbox to your Junk Email folder. 

What's phishing?

Phishing is the practice of luring you into disclosing personal information, such as bank account numbers and passwords. Often phishing messages look legitimate, but have deceptive links that actually open fake websites. If you select  Phishing, a copy of your message may be sent to Microsoft to help update our filters, and the message will be moved from your Inbox to your Junk Email folder.
