MicrosoftExchangePSTCapture enables a network administrator to search for PST files on computers in an organization and then import those files into mailboxes hosted in Exchange Online. PST Capture is comprised of the following components:
PSTCaptureCentralService. At the heart of PST Capture is the PSTCaptureCentralService. The Central Service maintains the list of all PST files found in an organization and manages the data as it is moved to Exchange Online.
PSTCaptureAgent. Discovery of the PST files is performed by PST Capture agents that are installed on client computers. The agents also send the PST files they find to the host computer when an import operation is started on the PST Capture Console.
PSTCaptureConsole.The PST Capture Console is the interface used to configure PST searches, specify the target mailboxes for PST files, and track the status of PST import operations and reports. The administrator can also use the console to import PST files stored on network-attached storage (NAS) devices, since PST agents cannot be installed on NAS devices. For optimal operation, the PST Capture Central Service and the PST Capture Console should run on a
dedicated computer, known as the PST Capture host computer.
