If a legitimate email does get sent to the Junk Email folder, you can train the filter not to view email from that sender as junk by selecting the message and clicking Home > Junk > Not Junk.Ī confirmation box will open telling you the mail will be moved to the Inbox and giving you the option to add the sender to the Safe Sender lists. If you want Outlook to be more aggressive you can go for the “High” setting, but this is very likely to move some legitimate email to the Junk Email folder, so you’ll need to check it regularly. You can switch to “Low” to catch more obvious junk email, and this setting should be enough for most people. By default, the junk email filter is set to “No Automatic Filtering,” so only emails from senders you’ve deliberately added to your Blocked Senders list will end up in the Junk Email folder. Email marked as junk is sent directly to the Junk Email folder, and you can choose how aggressively Outlook marks emails as junk. The Options tab on the Junk Email window is where you can set Outlook’s junk email options for any message that comes in. Click on this option to open the Junk Email Options panel.
