Microsoft has announced the end of support for TLS 1.0 and 1.1.
As of September 8, 2019 Microsoft Cloud App Security will no longer support TLS 1.0 and 1.1. This means that any connection using these protocols will no longer work as expected, and no support will be provided.
This gives customers still using the old connection protocol little time to migrate to version 1.2.
To see how this affects those still utilizing the older versions, see: End of support for TLS 1.0 and 1.1 in Microsoft Cloud App Security
