As per this article, in order to export mailbox contents from Exchange 2007, you need to use a 32-bit computer with the following software installed:
- Exchange 2007 management tools
- Outlook 2003 or Outlook 2007
The 32-bit requirement comes from Outlook, which until the 2010 release wasn't available as a 64-bit application, so it wasn't able to interact with x64 Exchange management tools.
However, Outlook 2010 has a 64-bit version; thus, my question: if I install Outloook 2010 x64 on an Exchange 2007 (x64) server, will I be able to directly export mailbox contents from there, without the need to deploy a 32-bit computer only for this task?

Massimo,
Unless something has changed over the years with some new patch or hotfix to 2007, and I don't think it has, it still won't work. The error will still kick out because it looks at the OS and not the app, looking for a 32bit OS itself. I recall having to go with a 3rd party program because of this issue in the past.
UPDATE: I found this: http://social.technet.microsoft.com/Forums/exchange/en-US/d2c41018-3dc3-44b8-b972-c74c72bdf07d/exch-2007-sp2-x64-exportmailbox-possible-w-outlook-2010-x64 and it appears to confirm the same issue still holds true:
