Pseudo-TLS is not impacted by disabling TLS 1.0/1.1 on Skype for Business Servers and an in-depth discussion of MS-TURN Pseudo-TLS is beyond the scope of this blog series. For more information see Preparing for TLS 1.0/1.1 Deprecation - O365 Skype for Business.Īlso note we have not made any changes to our Pseudo-TLS implementation. Note that we are not covering Office 365 in this series of blog posts with the exception of preparing your On-Premises environment to communicate with Office 365 in Hybrid or Federation scenarios once TLS 1.0 and 1.1 are deprecated. This information is authoritative and should be considered official Microsoft documentation from the Skype for Business Product Group.
