Exchange Team Blog: We're excited to announce that later this year we'll be adding a new tool to our already rich portfolio of planning and deployment tools. This new tool, PST Capture, will be downloadable and free, and will enable you to discover .pst files on your network and then import them into both Exchange Online (in Office 365) and Exchange Server 2010 on-premises. PST Capture will be available later this year. It doesn’t replace the New-MailboxImportRequest cmdlet that exists already for importing known .pst files into Exchange Server, but instead works in parallel to enable you to embark on a systematic search and destroy mission to rid yourself of the dreaded .pst scourge.
