PFF (cf. summary from the Forensics Wiki) is a format exportable from Outlook and Exchange. Outlook makes use of this format for different scenarios, and calls them different names (.pst, .ost), but it is just one file type.
.pst files can be generated with Outlook interactively
.ost files can be taken from C:Users…
.pst files can be also generated from an Exchange Server’s PowerShell in a mostly unattended fashion
Outlook interactive export¶
Once the Outlook main window is open, go to “File”, “Open & Export”, “Import/Export”:
Then follow the usual dialog chain.
On the grommunio system, PFF files can be imported on the command-line with gromox-pff2mt and gromox-mt2exm. These are two commands meant to be chained together by way of a pipe; tend to the linked manual pages to read about the invocation syntax.
Exchange PowerShell export¶
Contributors have written a PowerShell script for the mass export of .pst files from an Exchange Management Console (a PowerShell instance with Exchange commands loaded) with a subsequent mass import via ssh commands that it issues. Inspect the first 130 or so lines of the script for mandatory adjustable parameters.
