For reliable results in your archive

About Outlook True Archive


Outlook True Archive is a Windows program (for only $19.95) that does what Outlook itself cannot do – it truly archives your mail from an Outlook PST file (or OST or Exchange server account), with great ease and predictable results.

Unlike the built-in tool, Outlook True Archive eases the process of archiving your mails and calendar items. It has a clean visual system for making selections. It automatically remembers folders you selected previously. It is easy to use, as all archiving options can be simply selected.

For advanced users, Outlook True Archive offers a command line interface (included in the standard $19.95 package), so that tasks can be prepared by an IT-person and run systematically thereafter, either automatically or by a non-expert user.

Outlook True Archive archives mails items based on the date the mail was received or sent, rather than the date it was last modified. The benefit for you: reliable results in your archive.

Why you need this utility

Principally, our users have complimented the software for ease of use and the consistent, reliable results. The archives they create with Outlook True Archive contain exactly what they expected.

When you use Microsoft Outlook to archive a Mail message folder by date, Outlook determines the message age from the Sent timestamp, Received timestamp, or from the message’s Last Modified timestamp, whichever is later. As a result you may find that your messages are not archived because the Last Modified date/time has been updated.

The following actions will change the message’s modified date/time:

  • Forwarding
  • Replying
  • Replying to All
  • Editing and Saving
  • Moving or Copying

Copying or moving the message to another message folder does not always change the Last Modified timestamp; if the destination folder is a Personal Folders file (.pst), the timestamp does not change.

If the destination folder is an Exchange Server Mailbox or an Offline Folders file (.ost), the timestamp does change.
