Office and Outlook 365 Email - DoIT Best Effort Support Definition
Doit's statement on BYOD and Office Outlook 365 Support Clarification "Best Effort"
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?.
