As you know many resources on Azure support TLS, letting you also the choice between TLS 1.0, TLS 1.1 or TLS 1.2.
As you also probably know TLS 1.0 or TLS 1.1 are now the weakest versions and are also deprecated since 2021; meaning if you are using one of these version you are probably in security risk.
While it has been an Azure Advisor recommendation for quite some time to use TLS 1.2, Microsoft is now moving forward by removing support for these version and set the default version to TLS 1.2 for storage accounts.
This change will impact both new and existing storage accounts.
By November 1st, 2024 TLS 1.2 will become the default TLS version for storage account; you should start looking at migrating to TLS 1.2 and check and remove any dependencies with TLS 1.x version.
