Issue:
As of 16 September 2024, Microsoft no longer allows basic authentication for personal customers.  As a result, PowerChute can no longer connect to smtp-mail.outlook.com to send email notifications.

Basic Authentication support will be removed from Exchange Online accounts from March 2026 onwards.

See Microsoft article Exchange Online to retire Basic auth for Client Submission (SMTP AUTH)
