Exchange virtualization

A much asked question these days, is Exchange supported in a virtualized environment? As in many cases, the answer is “it depends”. Microsoft supports virtualized Exchange under the following conditions:

  • Hardware virtualization software used is one of the following products:
    • For Exchange 2007 or Exchange 2010: Windows Server 2008, Windows Server 2008 R2 with Hyper-V, Hyper-V Server 2008 or Hyper-V Server 2008 R2;
    • For Exchange 2003: Virtual Server 2005 R2;
    • In general, any validated 3rd party hypervisor (check for ESX, XenServer versions etc.). Click here for the list.
  • Exchange guest
    • Exchange 2003 SP2 (or later)
      • Virtual Machine Additions and Virtual Machine PCI SCSI driver required;
      • Exchange 2003 clusters aren’t supported;
    • Exchange 2007 SP1 (or later)
      • is running on Windows Server 2008;
      • support for Windows Server 2008 R2 expected with Exchange Server 2007 SP3 (no date announced yet);
      • No Unified Messaging role (due to real-time requirements by UM role);
      • Meets all of the Exchange 2007 SP1 specific requirements (here).
    • Exchange 2010
      • is running on Windows Server 2008 SP2 or Windows Server 2008 R2;
      • No Unified Messaging role (due to real-time requirements by UM role);
