While no longer supported, our servers still allow clients to use those older versions of TLS when connecting with Exchange Online. A balance is needed in a shared service that hosts the emails of local bakeries as well as many countries’ governments.

We know that the push to meet our security and compliance requirements has made it difficult to support legacy clients and devices that use our service. If you have clients that can’t use TLS1.2, they should be configured to use the opt-in legacy endpoint by now.Įxchange Online ended support for TLS1.0 and TLS1.1 in October 2020. Update (Feb 2022): We have started to disable TLS1.0 and TLS1.1 for the default SMTP AUTH endpoints. We will be disabling TLS 1.0 and TLS 1.1 usage with SMTP, starting by rejecting a portion of SMTP AUTH submissions using TLS1.0 or TLS1.1 and leading up to a 100% disablement. Update (April 2023): For Microsoft 365 operated by 21Vianet, TLS1.0 and TLS1.1 for SMTP AUTH will no longer be supported after June 30, 2023.
