outlook.pst is not a personal folders file in Windows 7 32bit using Office Outlook 2007

Not open for further replies.


Using windows 7 32bit & Office 2007 with Outlook. Had a recent back of my HD and encountered a crash, installed a new HD into Computer and a full reinstall of everything, but when trying to import my backed up Outlook.pst file I get an error that " outlook.pst is not a personal folders file" . I have also tried File, Open, Outlook data file and receive the same error message.

Tried to use Scanpst.exe and I received the same type of error " Inbox Repair Tool does not recognize the file. C\Users\Sunny\AppData\Local\Microsoft\Outlook\Outlook.pst. No information can be recovered." This file is over 2GB and I have to recover.

I have reviewed over 31 posts and replied to a few that were similar or same issues and no response as of yet. I saw a mention of " try using third-party Outlook PST Repair Tools, but the link returned a 404 error, page not found.

Any thoughts or suggestions?

Thank you in advance for your assistance,



Yes - don't use Import in the first place - it causes all sorts of problems. Seehere for more info about that.

Copy the pst file into your Documents folder. Right-click on it, choose Properties. Ensure that the Read-Only attribute is NOT checked.

Open Outlook and do File-Open-Outlook Data File and navigate to where you put it.

You can then either set that file as the default delivery location or copy the data to the new file.

For future info see here on how to migrate Outlook data correctly.

If you are using a legacy pst file from a version of Outlook prior to 2003 and you are getting the " Oversize" error then you need the pst cropping tool.

Get that here.

I am currently copying from my external HD the Outlook.pst file of 2.53GB to documents/outlook folder, it will take about 10 minutes.

I believe about a year ago I was using Office 2002 originally from Windows XP and had done the initial upgrade to 2007 and had used that 2002 outlook.pst file when originally setting up outlook 2007 and it worked ok, imported and archived but the only thing that wasn't working correctly was using the To,CC and BCC to access my contacts when sending email, and was never able to find the answer to correct this issue after doing the upgrade to Windows 7 back in March 2010. But I could access them, copy paste and still use my email anyway. Not sure if this has something to do with what I am encountering now on my reinstall.

At some point, I do believe I saw an error regarding the size of my archive.pst file, so I will check your link provided related to that issue while waiting for the coping to my documents/outlook folder finishes.

Thank you


I downloaded the Exchange 2000 Tool: PST2GB and when I went to select the file, it gave the same error, not a .pst file. I tried this on both my outlook.pst and my archive.pst same message.


Ok, I have copied the file to Documents/Outlook (created a folder called outlook) and opened Outlook 2007 and went to File, Open, Personal Data File and received the exact same message. " outlook.pst is not a personal folders file"

I really have to recover all of this data, its just not an option, its there, and used to work.

Any other recommendations, third party software recommendations, anything not already tried and attempted would be tremendously appreciated, and we now have someone else that responded on a different post, who is having the same issue.

Thanks again,



I have the same problem except I am using outlook 2003 and Windows XP. The Inbox repair tool keeps giving me the " The path is invalid, Invaild path file" error. Below is the file name I tried to use amongst others.


Thank you in advance.
