If you are planning to deploy the Microsoft Online Services Directory Synchronization tool (DirSync) for synchronization from Active Directory to Office 365, then we have some important news for you.
There’s a 32-bit DirSync client AND a 64-bit DirSync client available for download at the Office 365 Portal!
|Download the Directory Synchronization tool (DirSync) from the Office 365 Portal|
The 64-bit version of DirSync supports Windows Server 2008 x64 or Windows Server 2008 R2 Standard/Enterprise operating systems.
If you’ve already deployed the 32-bit version DirSync, there is no need to install the new client. “The 64-bit version of the directory synchronization tool shares exact functional parity with the existing 32-bit software.”
For additional information, please see the Office 365 Wiki article, Directory Synchronization tool 64-bit support.
