PST Capture
On 30 Jan 2012, the PST Capture became available as a free download.
PST Capture helps you search your network to discover and then import .pst files across your environment - all from a straightforward admin-driven tool. PST Capture will help reduce risk while increasing productivity for your users by importing .pst files into Exchange Online or Exchange Server 2010 - directly into users' primary mailboxes or archives.
If you are looking at managing PST files better or even removing them from the messaging environment, this is the tool for you.
