Intune is aligning to M365's timeline to support Transport Layer Security (TLS) 1.2 to provide best-in-class encryption, to ensure our service is more secure by default, and to align with other Microsoft services such as Microsoft Office 365. Office has published a support post here: https://docs.microsoft.com/microsoft-365/compliance/tls-1.0-and-1.1-deprecation-for-office-365?view=... that discusses much of the details related to this change. In this post, we share a list of the devices and browsers that will not be able to work with TLS 1.2. Note, none of these devices are supported today by Intune. However, the devices may still be receiving policy and checking into the service.
