Are you e-mailing invoices, statements, orders, or other documents out of Sage 100? Are you on Sage 100 v2017 or older? If you answered yes to both questions, Microsoft’s retirement of Transport Layer Security (TLS) versions 1.0 and 1.1 will directly affect you.
Transport Layer Security (TLS) is a protocol designed to provide secure communications over computer networks. Like all things in technology the protocol has received updates over the years and last month Microsoft announced their plan to discontinue support for TLS 1.0 and 1.1 as of June 2020.
“To provide the best-in-class encryption to our customers, Microsoft plans to discontinue the support for Transport Layer Security (TLS) versions 1.0 and 1.1 in Office 365 and Office 365 GCC as of June 2020.
We understand that the security of your data is important, and we’re committed to transparency about changes that may affect your use of the TLS service.
Microsoft TLS 1.0 has no known security vulnerabilities. But because of the potential for future protocol downgrade attacks and other TLS vulnerabilities, we are discontinuing support for TLS 1.0 and 1.1 in Microsoft Office 365 and Office 365 GCC.
As of June 2020, Office 365 will begin deprecating TLS 1.0 and 1.1 in worldwide environments. This means that starting in June 2020, any commercial and GCC clients, devices or services that connect to Office 365 by using TLS 1.0 and 1.1 will not succeed.”
Sage 100 versions, v2017 and earlier, use TLS 1.0 so once disabled by Microsoft failures to deliver documents such as invoices, orders, statements, and stubs will occur. If you are on version 2017 or earlier and emailing any documents from Sage 100, plan for an upgrade prior to June 2020.
Sage 100 v2018 also utilizes TLS 1.0, but Sage is releasing a patch for this version to keep things functioning. Paperless office was updated with Sage 100 v2019 so that version is not impacted by the Microsoft retirement.
Sage has stated there are no plans to release any type of correction for versions prior to Sage 100 v2018. If you are on Sage 100 v. 2017 or earlier and emailing documents from Sage 100, please contact us to discuss an upgrade.
