Best Tools for Merging and De-duplicating .pst Files?

Merging .pst files? You’re basically creating a bigger .pst file. If that’s your goal, tools exist out there, but remember, it’s usually best to keep them separate—especially since the legal team will just index them separately anyway. So it might not be worth the trouble.

There are a couple of options! Autopsy has a nice email parser that could help with this. It's a tool I used in digital forensics before, and it should work pretty well for organizing your .pst files. Just look into their documentation for the email parser module! Just keep in mind that FTK is more user-friendly but could cost a lot.

Honestly, if you can, just hand off the files as they are. Merging and manipulating the .pst files might put you or your company in a tricky situation later on, especially with legal stuff. Better to leave them intact and let the legal team handle it as needed. They're used to managing the data anyway.
