Microsoft has announced a significant change in its approach to securing Outlook this year. The tech giant is set to retire Basic Auth in favor of Modern Auth on September 16, 2024. This shift means that users will no longer be able to sign in to their accounts using only their username and passwords, a move aimed at bolstering Outlook security. Email clients that do not leverage Modern Auth will be unable to access the Outlook service. To ensure a smooth transition post-September deadline, users are advised to download any of the official Outlook apps, use the one included in Microsoft 365, or utilize Outlook 2021 or above if they have an LTSC license for Office.
Changes to Legacy Outlook Versions
Microsoft has reported that millions of customers have already migrated to the new Outlook for Windows app. With the majority of Windows Mail and Calendar customers making the switch, Microsoft has decided to sunset its legacy apps this year. These older versions will not be available or supported through the Microsoft Store past 2024. Customers are encouraged to transition to the new Outlook for Windows as soon as possible, which offers Modern Auth, Copilot integration, rich message editing, and more.
Additionally, Microsoft is phasing out the light version of Outlook on the web for older browsers. This retirement will take effect on August 19, 2024. Users will need to use at least Edge 79, Chrome 79, Firefox 78, Safari 16, or Opera 76 to access Outlook on the web.
Impact on Gmail and Cortana Services
For those who use Gmail in Outlook on the web via the left pane, a significant change is coming. After June 30, 2024, users will need to use Outlook for Windows or Mac to perform the same functionality. Similarly, all services dependent upon Cortana will run out of support at the same time. This move might seem overdue to some, considering that the voice assistant has been mostly inactive for over a year.
These changes underscore Microsoft's commitment to enhancing Outlook security and ensuring a more seamless user experience across its platforms. By retiring outdated authentication methods and legacy applications, Microsoft aims to provide a more secure and efficient service for its users.
