Our current system is installing Exchange 2016 on the Windows 2012R2 OS platform. We are planning to upgrade the OS to Windows 2016 -> I want to ask, will the Exchange system be affected? Do I have to reconfigure Exchange? Thanks to everyone for help

    This is not supported. You will need to build a new Exch Server with the supported o/s and move mailboxes etc to the new server.

    Yes, you need to build a new Exchange server and migrate mailboxes to it.

    Your Existing Exchange server environment: Exch01 (Windows 2012 R2, Exchange 2016)

    You can follow below steps-

    • Install a new Windows server 2016 (named Exch02)
    • Install Exchange 2016 latest Security Updates on Exch02
    • In Exchange Admin Center (EAC) :
    • Add Exch02 to the Send Connector
    • Select Exch02 > Configure External Access Domain URL the same as above and select Exch02 as the source server.
    • Select Exch02 > Configure Outlook Anywhere using the same domain
    • Configure OWA and other virtual directories with the same URL
    • External DNS:
    • Autodiscover points to Exch02
    • Install a new certificate for Exch02
    • Move mailboxes to Exch02
    • Test send/receive emails
    • Shutdown Exch01
    • Test send/receive emails
