Upstart is exactly the tool we’d been looking for to streamline our forensics and recovery processes. Thanks Pete!

Upstart
Upstart is a utility for converting and merging Outlook® PSTs. It converts ANSI PSTs to Unicode, Unicode PSTs to ANSI, unencrypted PSTs to encrypted and so on. In addition it combines arbitrary PSTs.
Key features
- For every conversion, Upstart creates a new PST that is a replica, folder by folder, of an existing one. It makes no changes to the original.
- Supports bulk conversions. You can save loads of time by converting dozens of ANSI PSTs to Unicode, or vice versa, in one shot.
- Converts oversized 2GB ANSI PSTs that Outlook cannot open (in most cases).
- Converts all the PSTs on a drive with one command. Great for PSTs on file servers! (Applies to Site and Enterprise editions only)
- Allows you to specify all available encryption options: none, compressible, high -- or match the original.
- Handles messages, Contacts, appointments, tasks, forms and views. (Outlook rules are a special case. Upstart handles rules in conversions with no problem but is not able to combine rules when merging PSTs.)
- Guaranteed free from adware, snoopware, and all things nasty.
- No installation step needed. Just download, unzip and run. You can carry Upstart around on a thumb drive or even a diskette.
Requirements
- The only essential requirement for using Upstart is Microsoft® Outlook 2003 or 2007
- A screen resolution of at least 1024x768
- We recommend using Upstart on a system that does not have Exchange Server or the Exchange Management Tools installed
- Upstart has some conflicts with OsaSync PRO and Lookout and should be used with caution if either of these tools is in use
