Looks like comms has been updated. https://support.microsoft.com/en-us/help/4057306/preparing-for-tls-1-2-in-office-365
As of October 31, 2018, Office 365 will no longer support TLS 1.0 and 1.1. This means that Microsoft will not fix new issues that are found in clients, devices, or services that connect to Office 365 by using TLS 1.0 and 1.1.
** Note ** This doesn't mean Office 365 will block TLS 1.0 and 1.1 connections.
Microsoft Surface Hub and Skype Room Systems Version 2 (SRS v2) currently use TLS 1.0 or 1.1, and they will continue to work after October 31, 2018. Microsoft will update Surface Hub, Skype Room Systems V2, Skype for Business Online, and server products to support TLS 1.2 before TLS 1.0 and 1.1 are deprecated for Office 365. These products are expected to support TLS 1.2 by the first half of 2019. Skype for Business Online and on-premises customers should not disable TLS 1.0 and 1.1 until that time if they are using these meeting and calling devices.
