October the 13th 2020 is not only the end of support for Office 2010 and Exchange 2010, it also signals that Exchange 2016 will transition into extended support.
Exchange 2016 will continued to be supported as per the lifecycle support policy.
The below excerpt from the Microsoft lifecycle page illustrates when Exchange 2016 will exit extended support in 2025.
Exchange 2016 will be serviced and supported as per the extended lifecycle support policy.
Cheers,
