Microsoft 365 - Server and Account Configuration Settings

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail/Calendar 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?.


  • Only use this document if the client you are attempting to configure is not listed within: Microsoft 365 - Setup/configure Outlook on mobile device or desktop computer.

  • For the best experience/support, we recommend that you connect to your Microsoft 365 account using Outlook on the web via a browser, or Outlook client for desktop/iOS/Android.

  • Mobile devices, when configured for your Microsoft 365 account via Exchange/ActiveSync protocol can be remotely wiped. After reading the information within the remote wipe document, if you have decided that you do not want to configure your device using Exchange/Active Sync protocol, you do have the option to connect via IMAP. If connected via IMAP, you will only have access to your email.

  • Modern Authentication (OAuth2) is required by any client/application connect to UW-Madison M365 service.
