Microsoft, or rather the relevant product teams, have today made a number of announcements regarding the Deprecation of various services.
\nHere is a summary of the announcements.<\/p>\n

The three most important points announced are as follows:<\/p>\n

\u00a0<\/p>\n

Abolition of Basic Auth for Outlook.com<\/h3>\n

Basic authentication is a common method that applications use to connect to servers, services, and API endpoints. It involves sending a username and password with every request, and storing or saving those credentials on the device. Most servers or services enable Basic authentication by default, and it is easy to set up.<\/span>\u00a0<\/span><\/p>\n

However, Basic authentication has some drawbacks. It makes it easier for attackers to capture user credentials, especially if the credentials are not protected by TLS (Transport Layer Security). This increases the risk of those stolen credentials being reused against other endpoints or services. Moreover, Basic authentication does not support or facilitate multifactor authentication (MFA), which is an additional layer of security for user accounts.<\/span>\u00a0<\/span><\/p>\n

After removing Basic Auth for Exchange online in commercial Microsoft 365 Tenants, Microsoft will now force <\/span>Modern Auth\/OAuth 2.0<\/strong> for Outlook.com<\/strong><\/span> as well<\/span>. <\/span>That <\/span>means<\/span> that all clients connecting to Outlook.com<\/strong> must definitely <\/span>use the new methods.<\/span><\/span>\u00a0<\/span><\/p>\n

\u00a0<\/p>\n

Reminder that Mail\/Calendar will no longer be supported by end of calendar year<\/h3>\n

Microsoft has announced that the Mail and Calendar Apps will be phased out by the end of 2024, transitioning users to the New Outlook for Windows.<\/p>\n

Users are currently able to test the New Outlook while retaining the option to switch between it and the Mail App versions. Supported Accounts<\/strong> include Microsoft 365 consumer accounts like Outlook.com, Hotmail.com, and Live.com, as well as Microsoft 365 work or school accounts and Gmail. Plans are underway to extend support to Yahoo!, iCloud, and other email providers through IMAP and POP in the future.<\/p>\n<\/div>\n<\/div>\n
