Please go here to search for your product's lifecycle.
For products falling within the Azure product categories outlined on the Azure product page, Microsoft typically offers a notification period of up to 3-years before discontinuing support unless stated otherwise.
Exceptions include free products, preview products, products with fixed lifecycles, and products that depend on integrated services, components, or tools that follow a different lifecycle and have published maintenance or support policies.
Select Dynamics products (listed below) also follow this notification subset.
