I´m using discryptor.net to encrypt my data. It is userfriendly and really fast.

My mistake. The compressible encryption is not a Caesar cipher, it is instead a byte substitution cipher with a fixed substitution table.

With respect to security, it does not matter which of the three so-called encryption options you pick, they are all essentially equivalent. Compressible encryption is a simple Caesar cipher (crypt = table[plain]) for each plain text byte with a fixed permutation table that does not depend on the password. Of course, since the permutation table is fixed, it is also known. Therefore, anyone can trivially decrypt these .pst files.

High encryption moves us all the way up to an early WWII German Enigma three rotor cipher, where again, the content of the three rotors are fixed and don't depend on the password. Of course, since the rotors are fixed and known, anyone can trivially decrypt these .pst files as well.

All in all, a complete joke as far as security is concerned.

In Outlook 2007 there indeed seems to be no option anymore to set no encryption! Why Microsoft makes a new Outlook version not compatible with the older versions?? Anyone knows a fix for this? In order to use certain programs like Pst2mail the pst-file should be set to no encryption.........

I found you through Google, please help. What's the difference b/w encryption "none" and encryption "AES-128"? I'm trying to use/format a brand new blank disk on my PC that has Microsoft Office Suite. Thanks so much!!

The file format is proprietary, and to the best of my knowledge, not published. You need outlook.

I do not believe that information is public. The appropriate way to do that would be to use the Outlook Object model and programatic API. Which requires outlook be installed and available, of course.

You shouldn't have to "import" it. Just open it in Outlook.

YOur right Leo, i found out that when you burn it to a CD it marks it "read ONly" i copied it off the CD and checked the properties and it was not checked as read only. But after checking and then unchecking the box, it worked

Has nothing to do with passwords. More likely the .pst file is marked "read/only" or it's open by another process.
