Microsoft and Google are retiring Basic Authentication by April 2026, a change that could affect how your phone and email systems work together. If you rely on voicemail-to-email, fax-to-email, or system alerts, these updates could stop those messages from sending, unless your system is modernized. Check out the rest of this page to learn more about this important update!
Starting March 2026, Microsoft and Google will discontinue support for Basic Authentication, the legacy username-and-password method used by many email servers. Full deactivation can be expected by April 30, 2026. This update impacts systems that connect to Outlook, Exchange, or Gmail, including voicemail, printer, and alerting integrations.
Without an update, those systems may no longer reliably deliver messages.
If your phone system sends voicemails to your inbox, this change could interrupt delivery. Gibson Teldata can reconfigure your system to use secure, supported authentication.
Printers, copiers, and other applications that use SMTP may fail to send messages after the update. We’ll help you implement modern, secure connections.
Modern authentication protects your network, aligns with Microsoft and Google standards, and ensures continuous, secure communication.
