Add modern authentication as a method for email alerts

Currently PMPC uses legacy authentication to authorize the sender account for email alerts. Allowing Modern Authentication would allow those whose clients specifically want to block legacy authentication to achieve the same level of support.

    Microsoft revised this timeline recently.

    https://techcommunity.microsoft.com/blog/exchange/exchange-online-to-retire-basic-auth-for-client-submission-smtp-auth/4114750

    Update 6/11/2025: We updated the timeline of this deprecation mentioned in this post.

    Exchange Online will permanently remove support for Basic authentication with Client Submission (SMTP AUTH) gradually beginning with a small percentage of submission rejections for all tenants on March 1st 2026 and reaching 100% rejections on April 30th 2026, (previously September 2025). After this time, applications and devices will no longer be able to use Basic auth as an authentication method and must use OAuth when using SMTP AUTH to send email.

    We're aware of this, and it is being discussed internally but there is no timeline to share for supporting OAuth at this time.

    Microsoft is retiring Basic Authentication for SMTP Client Submission in Exchange Online, and this change is scheduled to be completed by September 2025. This means that applications and devices relying on SMTP with basic authentication will need to switch to OAuth (Modern Authentication). The change is part of Microsoft's efforts to enhance security and protect customer data by retiring legacy authentication methods.

    Reporting has moved to Adv. Insights. Please give that a look and if you have any further Feature improvements, pop those in :)

    We also need this feature; I needed to disable multiple security features for our e-mail account in PatchMyPC to allow alerts and e-mail reports.

    Yes! I second this request. Microsoft is going to be blocking all legacy authentication methods so this is going to be a requirement for alerting.
