There seems to a way to get the vista version of ESM for E2K3 working on WS08 ->

...
Will test this out in the lab - what is the risk of inherited permissions now flowing down to EV and according to the EV Compatability charts it does say that WS08 is support in WOW64 i.e. EV installed itseld in Program Files (x86).
Windows Server 2008
x64 edition (using WOW64) SP1 N N N Yj, l
which means the SMTP agent is not supported and says to apply a hotfix - Requires Microsoft hotfix http://support.microsoft.com/kb/949516.
Basically I'm trying to move away from W2K3 and now this is like a gotcha. The below write on the Compatability charts regarding ESM is just so wordy and confusing i'm struggling to understand...
"Exchange System Manager (ESM)
Microsoft Exchange System Manager (ESM) is a prerequisite on the Enterprise
Vault server for Enterprise Vault 7.0 SP2 and earlier versions. See the following
subsections for more information.
Note: You cannot use Exchange System Manager on an Enterprise Vault server
to manage Exchange Server. The version of mapi32.dll used by Enterprise
Vault is not compatible with that required by Exchange System Manager.
Enterprise Vault versions where ESM is not a prerequisite
From Enterprise Vault 7.0 SP3 onwards, it is possible to run an Exchange
mailbox archiving task or Journaling task without installing ESM on the
Enterprise Vault server.
The ability to synchronize inherited permissions from the Exchange server to
users’ archives requires ESM to be installed on the Enterprise Vault server. Note
the following:
■ If ESM is installed on an Enterprise Vault server running 32-bit Windows
Server 2003, you can still synchronize inherited permissions from the
Exchange server to users' archives.
■ Windows Server 2003 x64 SP2 prevents Exchange Server 2003 ESM from
installing, so you cannot synchronize inherited permissions if the
Enterprise Vault server uses this operating system.
Enterprise Vault 7.0 SP3 and later versions of Enterprise Vault still include the
ability to synchronize delegate permissions; that is, permissions set through
Active Directory users and computers, or through Outlook folder permissions.
Enterprise Vault versions where ESM is a prerequisite
In Enterprise Vault 7.0 SP2 and earlier versions, Enterprise Vault servers with
an Exchange mailbox archiving task or Journaling task must have the ESM tools
and fixes shown in the table below.
Note: Exchange Management Console (the management tool with Exchange
Server 2007) is currently not supported on any version of the Enterprise Vault
server. To archive from Exchange Server 2007, install Exchange System
Manager for Exchange Server 2003 on the Enterprise Vault server. Outlook 2003
is also still required on the Enterprise Vault server, even if all of your target
Exchange servers are running Exchange Server 2007."
So what's this inherited permissions got to do with EV archives? Admins will have issues? etc..are they even being synced in the first place?
