You can send and receive Microsoft 365 emails using any Modern Auth/OAuth-compatible email client. Clients that support OAuth can take advantage of security features such as Single Sign-on and Duo two-factor authentication.

Below is a list of the most popular clients along with their minimum system requirements, where applicable.

• Apple Mail running on macOS 10.15 (Catalina) and above
• iOS Mail running on iOS 11.3.1 and above
• Microsoft Outlook 365, Outlook 2021, or Outlook 2019, any version (Outlook 2016 may not work due to known limitations)
• Microsoft Outlook Mobile, any version
• Mozilla Thunderbird version 78 and above

OIT cannot assist with the operating system or mail client upgrades.

• Students who use Microsoft Outlook can download a free copy of Microsoft Office 365
• Non-UCI Health faculty and staff can download a copy of Microsoft Office 365.

We also recommend Outlook Mobile for iOS or Android, which you can download from your mobile device's app store.
