Maybe I can add some details about my progress
If I Open the file as Binary and read bytes 24 to 32 I have found 00 04 00
00 in all the old style pst that I create from Outlook(Newer pst's differ
between each file in these bytes). This would do fine as a search criteria IF
I could be sure this is the case for all oldstyle pst's created with earlier
Outlook versions.
We are having backup problems with the "old" pst's on many users laptops and
I need to create a small app that can identify the pst file version on about
1000 laptops. Doing this manually is quite a task..
My problem right now is finding a large collection of oldstyle pst's to test
on.
