UCSF IT is enabling modern authentication in our Office 365 – Exchange Online tenant, including the Outlook email client on June 22. This provides more secure user authentication and authorization. Outlook email will be the biggest change for most people, especially Windows users, who will begin to see the new sign-on experience within 24 hours of the change. 

For more information and to see how the new experience will look, please refer to the Modern Authentication project page.
