Does the TLS 1.0/1.1 deprecation effect non-TLS relays/connectors?

Hello, does anyone know if the Monday January 11th deadline for removing TLS 1.0/1.1 also affect clients sending without TLS?  In other words, will clients/connectors not using TLS also stop working next Monday? Thanks!

  • Hi, not sure what you’re asking but the deprecation of TLS 1.0 and 1.1 is about connections to the Office 365 service.

      ChristianBergstromRight, I am asking if connections that do not use TLS will be rejected starting Monday. That is not stated in any MSFT documentation/blog posts but just looking to double check.
