If you have not yet updated your Azure AD Connect then it is time to start planning for the same. MSFT says that from Nov 2020, versions older than 18 months are going to be deprecated. Read on for more info.
”
Starting on November 1st, 2020, we will begin implementing a deprecation process whereby versions of Azure AD Connect that were released more than 18 months ago will be deprecated. At that time we will begin this process by deprecating all releases of Azure AD Connect with version 1.3.20.0 (which was released on 4/24/2019) and older, and we will proceed to evaluate the deprecation of older versions of Azure AD Connect every time a new version releases.
You need to make sure you are running a recent version of Azure AD Connect to receive an optimal support experience.
If you run a deprecated version of Azure AD Connect you may not have the latest security fixes, performance improvements, troubleshooting and diagnostic tools and service enhancements, and if you require support we may not be able to provide you with the level of service your organization needs.
If you have enabled Azure AD Connect for sync you will soon automatically begin receiving Health notifications that warn you about upcoming deprecations when you are running one of the older versions.
