Apple Mail - Exporting a Mailbox

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 will provide step-by-step guidance on how to export a mailbox from Apple Mail.
