Overview of the Junk Email Filter

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.

Tips: It’s a good idea to regularly review messages in the Junk Email folder to check for legitimate messages that were incorrectly classified as junk. If you find a message that isn’t junk, drag it back to the Inbox or any folder. You can also mark the item as not junk by doing the following:

  • Click Home > Junk > Not Junk.

You can block messages from specific email addresses or domains from reaching your inbox. When you add an email address or domain to your blocked senders list, Outlook on the web automatically moves messages from that sender to the Junk Email folder.

By default, the Junk Email Filter is turned on and the protection level is set to No Automatic Filtering. You can make the filter more aggressive by changing the level of protection that it provides. The Junk Email Filter evaluates each incoming message based on several factors. These can include the time when the message was sent and the content of the message.

To change the options for the Junk Email Filter in Outlook do the following:

  • Click Home > Junk > Junk Email Options.

Mac Outlook users do not have access to the Junk Mail Preferences on Exchange email, Junk mail filtering is handled via webmail.  View above “Stop messages from Specific people going to Junk“.

Quarantined Messages

As a user, you can view, release, and delete quarantined messages where you are a recipient, when the message was quarantined as spam or bulk email.
However, messages that were quarantined for known phishing attempts, malware, or by mail flow rules are only available to admins.  End users will not be able to view or release these emails and will have to contact the Service Desk
