Office 365 (Apple Mail) - Junk Email and Phishing

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result.

Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?.

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 Office 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.
