Overview of the Junk Email Filter
Applies To: Outlook for Microsoft 365 (Windows), Outlook on the web
No one likes spam or junk email. The Outlook Junk Email Filter helps reduce unwanted email by automatically moving suspected spam to your Junk Email folder. While the Junk Email Filter cannot prevent all unwanted messages from reaching your mailbox, it helps keep your Inbox organized by separating suspected spam from legitimate email.
Microsoft 365 also uses Exchange Online Protection (EOP) to scan incoming email before it reaches your mailbox. As a result, some unwanted messages may be delivered to your Junk Email folder, while higher-risk messages may be quarantined before they appear in Outlook.
Tip: Review your Junk Email folder regularly to ensure legitimate messages have not been incorrectly classified as junk.
Mark a Message as Not Junk
If a legitimate email has been moved to your Junk Email folder:
- Open the Junk Email folder.
- Select the message.
- On the Home tab, select Junk > Not Junk.
- Follow any prompts to trust the sender if appropriate.
The message will be moved back to your Inbox.

You can customize how Outlook handles suspected junk email.

Can't Find an Expected Email?
If an expected email is not in your Inbox or Junk Email folder, it may have been quarantined by Microsoft 365 before it reached Outlook.
