I migrated a users data from one computer to another. He has 4 .pst files that I tried to map. the first one mapped ok but the next three game the the "the .pst is not an Outlook data file (.pst)" error. I tried running the scanpst application but got the same type error so the scanpst did not work. Any suggestions would be greatly appreciated.

Thank you.

Since scanpst does not work, you may try third-party Outlook recovery tools to repair your PST files, below is a list of them:

Nearly all these tools provide a free trial so you can try first to see if a tool works before purchase it.


Good luck!

Just to possibly save you some time, can you please check the file size of th PST file? I've had some cases where the file size shows up as zero, which means that there is nothing you'll be able to do to recover it. I've seen this happen a few times, and I haven't been able to figure out what's causing this to happen.

I did check the file size and they are all in excess of 2GB.

In that case, is it possible that the version of outlook on the old computer is newer than the one on the new computer? If so, then you'll need to install the newer version of outlook to open those files. Otherwise, you'll have to buy a program to try and recover data from those PSTs.

Both computers have Office 2010.

Then those fines got corrupted somehow, and you'll have to use recovery software to get anything out of them

"He has 4 .pst files that I tried to map"
Map meaning what?  Tried to open at \\somecomputer\somshare\somefilename ?
PST files are never meant to be accessed via a network share.
You can do it, but they eventually break and get corrupted.

You're dealing with Office 2010 -- which means newer computers.
Surely you have Previous Versions available!
Right-Click | Properties | Previous Versions and then choose Copy.
Copy them somewhere on the local drive.
Then see if they can be opened.

By mapping I mean that they were migrated to the new computer and I was trying to add them as data files so they would be accessible through Outlook on his new computer. I am not trying to access them via a network share.

I will try the previous version suggestion and let you know.
