Effective October 1, 2022, Microsoft will begin turning off Basic authentication as planned for Outlook, Exchange Web Services (EWS), Exchange Active Sync (EAS), Post Office Protocol (POP), Internet Message Access Protocol (IMAP), and Remote PowerShell (RPS). WPI cannot delay decommissioning.
Basic authentication means the application sends a username and password with each request, and those credentials are also often stored or saved on the device, which is a serious security vulnerability. Also, in most cases, Multi-Factor Authentication (MFA) is not possible with Basic authentication. Most modern 3rd party email clients support modern authentication (OAUTH).
SMTP Auth will not be disabled.
Impacted services include, but are not limited to:
- Any email client that uses POP or IMAP
- Native email clients on iOS or Android
- Outlook 2016 for Mac and Outlook 2013/2010 for Windows
- Versions older than Thunderbird 78
- Non-GUI clients (e.g., Pine)
