How to label messages as "Junk" in Outlook for Mac

The junk e-mail filter in Outlook sometimes classifies non-junk messages inaccurately. You can quickly reclassify messages if you need to.

Do any of the following.

Label a single message or multiple messages as "Junk”

1. Select in the reading pane, or open the message or messages you wish to classify as junk.
2. On the Home tab, click Junk, and then click Junk or Mark as Junk.

Note: Clicking the Junk button does not instruct Outlook to classify similar messages as junk. To help filter messages more accurately, you can increase the level of junk e-mail protection or create a rule that sends messages from the same sender to your junk folder.

Label a message as "Not Junk"

1. In the message list in your Junk Folder, select the message or messages you wish to classify as "Not Junk."
2. On the Home tab, click Junk, and then click Not Junk or Mark as Not Junk.

1. OR Open the message you wish to classify as Not Junk. If Outlook filters suspect the message may be junk, you will see the below message. Click Mark as Not Junk.
2. The message is moved to the Inbox folder of the mail account and removed from the Junk category.

Note: Clicking Not Junk or Mark as Not Junk does not instruct Outlook to classify similar messages as non-junk. To help prevent legitimate messages from reaching the junk folder, you can add a sender to your Outlook contacts or classify all messages from a sender's domain as non-junk. If you are on a mailing list, you can use Mailing List Manager to make sure that messages are handled by a mailing list rule and not classified as junk.
