As of Friday, Sept. 9, 2022: 

This is an update to the original Microsoft Authentication & TLS Update – Sage 100

Sage received updated guidance from Microsoft specific to the use of SMTP Auth for email integration between Sage 100 and Exchange Online. While Microsoft will block basic authentication for many online services, active accounts using SMTP Auth will not be impacted by their actions as originally announced to begin October 1, 2022. This means that Sage 100 customers utilizing in-product email services to send quotes, invoices, etc. do not face a shutdown of this functionality beginning on October 1, 2022. 

While this guidance also applies to other applications (like Sage Intelligence) that utilize SMTP Auth for email communication, customers need to be aware that many online services will be impacted; so, while Sage 100 is safe in the near term, other client applications using POP, IMAP, etc. can be impacted starting October 1, 2022.

The latest information from Microsoft, including which services are impacted, can be found here.

While this new guidance reduces the urgency of upgrading for Sage 100 customers on older releases, Microsoft continues to push toward the elimination of basic authentication to protect their customers. Sage strongly recommends that all customers be on a version that supports OAuth to reduce the risk of data breach and leverage additional security updates built into newer versions of our software. 

Your Next Steps

If you experience a sudden loss of functionality in your Sage 100 solution, please contact the ACC Software Solutions’ technical support team to promptly address the situation. Furthermore, if you are on an outdated version of Sage 100, the ACC team and Sage are strongly encouraging users to upgrade to a newer version of the Sage 100 software.
