I open it in Outlook on a current Windows. There was this fellow with XP, older Outlook that didn't reveal that for a long discussion.
So back to Outlook and export as needed. Works everytime for me.
A client of mine runs an 8gb pst file which I have finally encouraged him to reduce by archiving off all pre 2013 communications.
But before we do this i would prefer the pst file to be error free which it isn't. Whenever I run scanpst on the file it gets to the point of copying the pst before making changes, the copy is good but then scanpst hangs. Scanpst can only be killed by end process in task manager.
So of all the multitude of outlook pst file error recovery programs "out there" could I have some recommendations of which might be the correct tool. I have warned the client that it might cost £100 to purchase a program.
