PSTCompress is a powerful application that provides a reliable and comprehensive solution for PST File Management and attachment compression with automatic pst file compaction.

PSTCompress is a smart and effective Windows application that can decrease the size of all (personal folders) PST files created by Microsoft Exchange and Outlook 2000, XP, 2003 and 2007 by up to 95%.

The PST size reduction is done in two steps. In the first step PST compress recovers space in the PST file using a e-mail management policy. This policy allows PSTCompress to:
- Zip e-mail attachments by age and size. The attachments are still stored in the PST file but are smaller since they are now in zip file format.
- Store e-mail attachments to disk and strip them out of the e-mail. The attachments are no longer stored inside the PST file, but on disk. The attachment can be zipped before it is stored to save disk space or stored in it's original format. A link is placed in the e-mail so the attachment is still accessible from the e-mail through Outlook.
- Eliminate duplicate attachments when storing them to disk
- Delete e-mail attachments by age.
- Empty the deleted items folder.
- Delete sent item attachments and put a reference in the e-mail to the path of the original document. (Which probably still exists in that path)
- Delete sent items by age (E-mail and attachment)

In the second step, PSTCompress runs an Outlook compaction on the PST files. This step eliminates all the "dead" space in the PST file, including the space saved by compressing the attachments. The result is a reduction in PST file size of up to 95%.

Moreover, the powerful PSTCompress software can be run interactively, from the command line or scheduled to run in batch. PSTCompress has been designed to process PST files completely automated way.

Furthermore, with the help of PSTCompress, the administrators have the option to easily compact single PST files, but also thousands of PST files according to a schedule.

PSTCompress interfaces with the Windows Task scheduler to kick off a scheduled PSTCompress task automatically and when there is not enough time to complete, the schedule will continue at the next interval. PSTCompress also supports processing password protected PST files. In addition, PSTCompress can produce reports in HTML, text and CSV to show what was done.

Limitations:

- 15 days trial / 5 PST files limit / runs limit
