Browser Updates to TLS and how it will Impact Microsoft Dynamics CRM

Microsoft, Google, Apple, Mozilla and other major technology vendors are deprecating support of TLS versions 1.0 and 1.1 in 2020.  Popular web browsers will continue to function but start showing alerts when TLS 1.0 or 1.1 web communication is encountered, and server-to-server communications will also change.

Transport Layer Security (TLS) is a security protocol to encrypt and authenticate secure connections across the web, either from a web browser or between web servers. TLS version 1.0 was first defined in 1999, and version 1.1 was introduced in 2006. Due to evolving regulatory requirements and new security vulnerabilities, technology providers have been deprecating their support of TLS versions 1.0 and 1.1.

Impacts to Microsoft Dynamics 365/CRM

If you are running the cloud version of Microsoft Dynamics 365 (current version) you will not be impacted.

You WILL be impacted if 

Your organization uses CRM 2015 or older on premise. CRM 2015 and older use TLS 1.1 by default. In order to avoid TLS alerts or errors, take one or more of the following steps.

Update your CRM server environment.
Upgrade your CRM system to 2016 or higher.

Your organization or an IT provider hosts websites, microsites, or web applications on local web servers that are still using TLS 1.0 or 1.1. In order to avoid TLS alerts or errors, update your web server(s).
