Mark a Message as Junk in Outlook

Outlook Online filters most of the spam headed to your inbox to the Junk Email folder. Occasionally, some spam or other types of junk email makes it to your Outlook.com inbox. When unwanted mail shows up in your inbox, move it to the Junk Folder. You'll train Outlook.com to identify similar junk emails so that it automatically moves these message to the Junk Email folder.

Instructions in this article apply to Outlook.com and Outlook Online.

How to Mark a Message as Junk 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 and log in to your account.

  2. Go to the Outlook.com message list and select the junk message. To flag multiple messages as spam at one time, place a checkmark in the circle next to the message.

  5. In the Report as junk dialog box, select either to Report or Don't report the message to Microsoft.

  6. The message moves to the Junk Email folder and Outlook.com learns which types of messages you consider to be junk.

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

Use Junk Email Filters

If Outlook.com moves emails that are not junk to the Junk Email folder, place the senders on the Safe senders and domains list.

If the email comes from a mailing list, it may be identified as junk because your email address does not appear in the To line. If you trust the mailing list, add their address to Safe senders and domains list.

To add an email address to the Safe senders and domains list:

  1. Go to Settings.

  2. Select View all Outlook settings.

  4. In the Safe senders and domains section, select Add and enter the email address of a sender or domain from which you want to receive email messages.

    If Outlook doesn't recognize a junk mail sender and doesn't move their messages to the Junk Email folder, add the sender or domain to the Blocked senders and domains list.

  5. Select Save.
