Yes, Harvester can search and collect Outlook OST files.
When creating a job, there are options to include Loose OST’s (OST files that are not attached or active), Mounted OST’s (OST files that are attached to a Microsoft Outlook account), and Live OST’s (OST files that are attached and open).
NOTE: Unless “Generate loose email files from source” is selected, output for OST’s will be in PST format.
When selecting loose and mounted OST’s for collection, there are 3 options for OST processing which include:
– “Single target per source” – Creates a target PST for each source OST encountered
– “Collate sources into a single target PST” – Creates a single target PST of all source OST’s encountered
– “Generate loose email files from source” – Creates a single loose message file based on the format selected
Export types (for “Generate loose email files from source”):
– Unicode Outlook message files (.msg)
– Raw RFC822 files (.eml)
In order to collect live OST’s, Harvester uses a utility called VSS (Volume Shadow Services) to create a Shadow Volume of the source(s) listed for collection. This allows files that are normally locked (not able to be accessed or copied) to be enumerated and copied. Harvester 4.0.3028 and newer will automatically attempt a VSS copy for files in use (Harvester must be run as Administrator).
NOTE: Harvester is not compatible with OST’s created with Outlook 2013 or newer. These OST’s must be mounted using Outlook, or converted to PST using an OST-to-PST converter.
