Previously, Sage announced that Microsoft would disable the basic authentication services that enable in-product emailing from within Sage 100 and that an upgrade would be necessary by October 1, 2022. However, Microsoft has since issued updated guidance that extends the original deadline a bit.

The updated guidance is specific to Sage’s use of SMTP Auth (basic authentication) for email integration between Sage 100 and Microsoft Exchange Online. While Microsoft still plans to disable basic authentication for many online services (and subsequently require the use of modern authentication, or OAuth), active accounts using SMTP Auth will not be immediately impacted by their actions as originally announced.

In short, Sage 100 customers no longer face an immediate shutdown of in-product email services (i.e., emailing quotes and invoices to customers) on October 1, 2022.

While this new guidance reduces the near-term urgency of upgrading Sage 100 to a more current release, Microsoft will continue phasing out use of basic authentication. So, Sage strongly recommends that you upgrade to a version of Sage 100 that supports the newer OAuth as soon as practical.
