Microsoft announced that it will stop TLS 1.0/1.1 support for Azure accounts on November 1, 2024

Microsoft announced that starting on November 1, 2024, it will stop supporting Transport Layer Security (TLS) versions 1.0 and 1.1 for existing Azure accounts in the cloud. This move is intended to improve security and ensure that the minimum TLS version supported by Azure is TLS 1.2.

This change will affect all existing and new Azure accounts using TLS 1.0 and 1.1. To ensure that applications connecting to Azure Storage are not disrupted, we recommend migrating to TLS 1.2 and removing dependencies on TLS 1.0 and 1.1 by October 31, 2024, if possible. This ensures that your application's connection to Azure remains secure and stable.

Microsoft says TLS 1.0 and 1.1 do not support modern encryption algorithms and cipher suites; many Azure customers are already using TLS 1.2.

In fact, Microsoft announced in September 2023 that TLS 1.0 and 1.1 would be disabled by default in Windows 11. To address the backward compatibility needs of some enterprise customers, Microsoft is also providing the option to re-enable support for these older TLS versions.

In addition, Microsoft has removed support for TLS 1.0 and 1.1 in its Edge browser as early as 2020. Then in September 2022, Microsoft disabled these protocols, including Microsoft Internet Explorer and EdgeHTML browsers.
