security transition

The security transition tag covers discussions about moving from legacy authentication methods to more secure alternatives, particularly in Microsoft Exchange Online. A key topic is the extended deprecation timeline for Basic Authentication (SMTP AUTH), now set to begin March 2026 and complete by April 2026. This extension gives organizations more time to adopt modern authentication protocols. The tag focuses on practical migration steps, security implications, and compliance requirements for enterprise IT environments. Recurring themes include authentication deprecation schedules, secure protocol adoption, and administrative guidance for a smooth security transition.
