Office 365 (Apple Mail) - Categories

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 how to assign categories using Apple Mail. These instructions are for Mac OS 10.9, but are likely to be similar for Mac OS 10.5-8.

To assign a category to a message:

  1. Select the message you would like to assign the category to.
  2. In the toolbar, click the Flag icon.


  3. Pick a colored flag to assign to the message.
  4. The message, while remaining in its original location, will also appear in the Flagged mailbox, where you can show or hide messages based on their flag color.
