Microsoft 365 (Apple Mail) - Junk Email and Phishing

This document explains about junk email and phishing using Apple Mail. These instructions are for Mac OS 10.9, but are likely to be similar for Mac OS 10.5-8.

Office 365 Team Junk Mail Filtering Recommendation: It is the recommendation of the Office 365 team for users to disable all local client (Outlook, Apple Mail, etc.) automated junk mail filters and local client rules/filters in Office 365. For UW-Madison users, many clients will have local junk mail filtering disabled entirely. All rules/filters should be created in Outlook on the web. Please refer to our Microsoft 365 (Outlook on the web | Outlook for Windows/MacOS) - Using Inbox Rules document.
Apple mail evaluates each incoming message to assess whether it might be spam, based on several factors. If it is deemed as junk mail or spam, it will be moved to your Junk mailbox.


To access Junk E-Mail Filter Options:
  1. Go to Mail, then Preferences.


  2. Go to the Junk Mail tab.


  3. Adjust the settings as appropriate.
  4. To customize it further, check Perform Custom Actions and click Advanced.
    • Once finished, click OK.
Also note:
  • A folder you have marked as junk can be marked as Not Junk in the toolbar as well as above the message.



  • You may also create a rule that filters (moves or deletes) mail.
  • If a legitimate message appears in your Junk mailbox, drag the message out of the mailbox to remove its Junk status.
