Hi Roice,

There is nothing mentioned from
Microsoft:http://technet.microsoft.com/en-us/l.../aa998911.aspx

That's exactly the document that I meant: There is stated the
following:

Deemphasized Functionality
CDO 1.2.1 - This functionality is provided by the Exchange Web
Services.
MAPI32 - This functionality is provided by the Exchange Web Services.

Sorry - I stopped reading at this one:
MAPI client and CDO 1.2.1 on the Exchange installation
Exchange 2007 no longer depends on these components. They are a separate
component that will be available for download. For more information about
how to download the required components, see Microsoft Exchange Server MAPI
Client and Collaboration Data Objects 1.2.1

So you do not get MAPI installed on the Exchange Server itself. But you can
happily install the ExchangeMAPICDO package or even Outlook to get MAPI on
the server. But more important to me is that MAPI access to the server is
working and there is no statement that MAPI client access id deemphasized.
At least as long as Outlook Clients are supported there should be MAPI
access guaranteed.

You might get an answer from Microsoft (mainly Stephen Griffin) when you ask
this question in ms.public.win32.programmer.messaging
