Office 365 DirSync 64bit based on FIM 2010

Office 365 for 64bit servers (2008 and 2008 R2) is here.

Still best practice is to have at least one of those servers for a setup with federated identities and Exchange rich-coexistence:
- ADFS server (plus ADFS proxy oder TMG or similar)
- DirSync server
- Exchange 2010 Hybrid server

btw: If you try to install DirSync 64bit on a Windows 2008 R2 DC you will see this message.

And it has still the same "scary" error about MSOLCoExistence registry key. Run the config wizard with elevated rights.

Error: Access to the registry key 'HKEY_LOCAL_MACHINE\Software\Microsoft\MSOLCoExistence' is denied.
