Earlier in the year we shared information about our plans to remove support for Transport Layer Security (TLS) versions 1.0 and 1.1 by the end of October 2018 in line with Microsoft's plans for O365.
RM Unify and Transport Layer Security
The CC4 team in RM has now released a software update (CC4UPD212) to help CC4 customers to ensure that users will be able to continue using RM Unify and Microsoft O365 on all CC4 computers. TLS 1.2 is enabled by default on Windows 8.1, Windows 10, Windows Server 2012 and 2016. This update will ensure that TLS 1.2 is also enabled on Windows 7 computers and on Windows Server 2008 or 2008R2. As long as TLS 1.2 is supported and enabled on your device then your browser will automatically use the latest version of TLS when you access RM Unify or O365.

For CC4 customers, we recommend that you install CC4UPD212 as soon as possible to prepare for the changes to RM Unify and Microsoft O365.
For all other customers using Windows 7 computers, we recommend that you follow the instructions provided by Microsoft to ensure that all of your Windows 7 computers have TLS 1.2 enabled:
