Does Exchange Server 2016 have a fixed lifecycle policy?

Excuse me, could you clarify for me if Exchange Server 2016 adheres to a definitive lifecycle policy? I'm curious to know if Microsoft has outlined a specific set of guidelines or timelines for the support and eventual retirement of this version of their Exchange Server software. It would be immensely helpful to understand the longevity of this platform and any potential future changes or upgrades that may be necessary.
