    This is the official guidance:
    https://learn.microsoft.com/en-us/exchange/plan-and-deploy/system-requirements?view=exchserver-2016#hardware-requirements-for-exchange-2016
    You will notice there is no difference for a physical or VM, so in your case, set it
    32 GB of RAM or more installed: 32GB plus 10MB (32,778MB)

    The paging file size is set that way so it you can get a full memory dump in case of a crash.
    You do not absolutely have to set it that value, its just recommended.

    Hope that helps!
