Office 365 (Apple Mail) - Create a Message

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 create a message using Apple Mail. These instructions are for Mac OS 10.9, but are likely to be similar for Mac OS 10.5-8.

To create a new message:

  1. Click Compose New Message in the upper left.


  2. In the To or Cc field, type the name of anyone in your contacts or the appropriate email addresses.


  • Add a subject.


  • Type in the message you want to send.
  • After you have composed the message, click Send Message in the upper left.
