    TLS 1.0 and TLS 1.1 support will be discontinued on September 24, 2020

    Posted: 29 Aug 2020
    Microsoft builds and supports a variety of software products for Linux systems and makes them available via package repositories on To support modern security standards, will discontinue support for package downloads over Transport Layer Security (TLS) 1.0 and 1.1 protocols as of September 24, 2020. This means that any connection using these protocols will no longer work as expected, and no support will be provided. In order to continue to access packages from after that date, organizations will need to enable TLS 1.2 (or a later version). Where possible, Microsoft recommends that organizations remove all TLS 1.0 and 1.1 dependencies in their environments and disable TLS 1.0/1.1 at the operating system level.

    In the dazzling array of services among the Microsoft cloud offerings, the rollout of TLS 1.0/1.1 deprecations is not being done all at once. This has lead to some confusion and questions around which endpoints are dropping the older TLS support and when.

    Here I want to provide some dates and times of the endpoints, along with some .NET code guidance on how to use the newer TLS protocol (1.2), with some more information on TLS across the Microsoft Cloud.

    So to begin, here are some of the endpoints that we know of.

    Service end date Release
    Office 365 (Exchange/SharePoint/etc)
    Office 365 Dod/GCC 1/1/2020
    Office 365 consumer 10/15/2020
    Graph Government 8/5/2020
    Graph Consumer 10/15/2020
    Azure Guest OS images 1/1/2019 Family 6 release
    Azure Application Proxy 1/31/2019
    Azure intra-service traffic 1/1/2020
    Azure SQL DB managed instance (pre SQL 2016) 1/1/2020
    Azure Cosmos DB 7/29/2020
    Azure File Sync 8/1/2020
    Azure AD registration service in all sovereign clouds (GCC High, DoD etc.) 8/31/2020
    Azure Automation 9/1/2020
    Azure AD registration service in all commercial clouds 10/30/2020
    Azure App Services (Web apps/functions/etc.) no announced timeline, can be set by admin still. ??

    Thank you,
    I am working on a proposal, I know nothing, hoping you hold my hand.
    1. Any reason why you suggest 1.2 version of TLS when 1.3 version is available with some security related fixes.
    2. If we have Sharepoint, Citrix and other third party applications, servers, Azure etc, what is the impact of not moving to 1.3 or 1.2 ?
    3. What does it actually mean by microsoft will begin deprecations of TLS1.0/TLS1.1.. In terms of No security upgrades ? or functionality not working anymore with the third party vendors, if they move to new version or as a company, there is cyber security risk and so it is mandated to move ?
    3. As an organization to consider in my Planning, Can we have some applications on Sharepoint move to 1.2 and a few remain say 1.3?
    4. Does this mean, when we move to TLS 1.2 as you suggested, we do not have to worry about about disabling TLS1.0/TLS1.1 services?
    5. What is the financial impact in terms of benefits to upgrade and negative impact of not upgrading?

    Sorry a lot of questions but I am writing a justification document and I need some insight.
    happy to read any links you provide.

    Thanks in Advance.
