À compter du 31 octobre 2018, Office 365 ne prendra plus en charge les versions 1.0 et 1.1 de TLS, les clients/devront supporter TLS 1.2.

Cela prends beaucoup de notre temps ces derniers jours/semaines pour aider nos clients a être prêt le jour J afin de ne pas vivre une perte de service.

Microsoft vient de publier une mise a jour contenant des informations importantes:

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. There is no official date for disabling or removing TLS 1.0 and 1.1 in the TLS service for customer connections. The eventual deprecation date will be determined by customer telemetry and is not yet known. After a decision is made, there will be an announcement six months in advance unless we become aware of a known compromise, in which case we may have to act in less than six months to protect customers who use the services.
