PSA: EOL for TLS 1.0/1.1 support in Intune and Office 365

[German]Short information for administrators managing Windows systems with Microsoft's Intune. Microsoft is phasing out support for TLS 1.0 and TLS 1.1 (for security reasons) in the fall of 2018. Home and end users are not affected by this change, and can only remain locked out by https connections to the products in question.


I came across this information via Twitter. Support for the Transport Layer Security Standards TLS 1.0 and TLS 1.1 will end on October 31, 2018 for both Intune and Office 365.

Within this Technet blog post Microsoft announces that Intune will only support TLS 1.2 from October 31, 2018. Microsoft Office 365 can then also only communicate with TLS 1.2 via https encryption (see also). For administrators in corporate environments, this means that a number of devices and software products can no longer be used from October 31, 2018 due to the lack of TLS 1.2 support. For Office 365, Microsoft lists the following products as no longer compatible:

  • Android 4.3 and earlier versions
  • Firefox Version 5.0 and earlier versions
  • Internet Explorer 8 10 in Windows 7 and earlier versions
  • Internet Explorer 10 for Windows Phone 8.0
  • Safari 6.0.4/OS X10.8.4 and earlier

This list is further refined in the linked Intune-Technet article, so that the following product list has been compiled.

  • Android 2.3.7
  • Android 4.0.4
  • Android 4.1.1
  • Android 4.2.2
  • Android 4.3
  • Baidu Jan 2015
  • IE 7 / Vista
  • IE 8 / XP
  • IE 8-10 / Win 7
  • IE 10 / Win Phone 8.0
  • Java 6u45
  • Java 7u25
  • OpenSSL 0.9.8y
  • Safari 5.1.9 / OS X 10.6.8
  • Safari 6.0.4 / OS X 10.8.4

Apart from Safari, no Apple product is on the above list. But there is another special case in the Apple cosmos. The manufacturer from Cupertino had already announced a change to ATS (contains TLS 1.2) over a year ago. According to Microsoft, Apple has not yet taken this step. Microsoft has listed the 'shiny Apple story' on this website and stopped adding update information on April 7, 2018.
