Take steps to reduce the junk mail that reaches your inbox

Occasionally a junk email or two shows up in the inbox, but the majority go to the Junk Email folder automatically. At the same ​time, only a few legitimate emails are filtered to the Junk Email folder by mistake. To keep the number of mistaken spam messages low, select the Standard junk mail filter instead of the restrictive Exclusive filter.

Other Ways to Reduce Spam

Although the junk mail filter is helpful, try these other actions to reduce the spam you receive at

  1. When a junk email makes it to your Inbox, select the message, go to the navigation bar, and select Junk and then in the menu that appears, select Junk again. Outlook learns from this action and sends similar emails to the Junk folder in the future.

  2. Don't reply to spam or unsubscribe from spam messages. 

  3. Add email addresses or domains from junk email to the Blocked Senders list to send them directly to the Junk Email folder. 

  4. Add people or domains that you always want to receive email from to the Safe Senders list.

  5. Protect yourself from automated programs that gather email addresses from public message boards, chat rooms, or other public web pages by spelling out the entire email address such as Example AT Outlook DOT com when you leave comments on these sites.
