Windows 7: Outlook PST file too large

Outlook PST file too large

I had to re-install Windows 7 on my computer as I had to replace the motherboard. I backed up my outlook.pst file (2.3 gb) to a DVD and after installing Office 2007, I copied the PST file to my desktop. Now when I try to import it or read it using Data Management, I get a message saying this is not a personal folder. I know there are tools out there that can manage larger pst files, but I'm not sure which to use.

I may be misunderstanding your problem, but did you try "Open Outlook Data File" instead of "Import..."?

What is the exact wording of the error message?

Some information below to help you resolve the problem - please post back to let us know the results:
Not a personal folders file |

The pst-file is on a CD/DVD or other read only medium or is marked as "Read Only"
Outlook needs read/write access to a pst-file in order to connect to it. Therefore you must first copy the pst-file from the CD/DVD back to your local hard drive. I suggest you put the pst-file in a subfolder of your Documents folder and call that folder "Outlook". Make sure you donít overwrite any existing pst-files.
After copying right click the pst-file and choose Properties. Here verify that the "Read-only" file attribute is not selected.

Donít import! Donít import! Donít import!
Am I clear? Donít import! Once youíve restored the pst-file via the above method donít use import to make the pst-file available in Outlook. The proper method to open a pst-file is to connect to it via File-> Open-> Outlook Data FileÖ

Use scanpst.exe to scan it for errors
Still no luck? Then use use scanpst.exe to check the pst-file for errors. The location of scanpst.exe depends on your version of Outlook and Windows. See this post to find the location for your version.

Use a 3rd party recovery tool
When scanpst.exe is unable to fix the pst-file there might have been some serious corruption in the pst-file. There are some 3rd party recovery tools available like OutlookFIX. These tools are specialized to try to recover every single recoverable item from your pst-file. Be warned; these tools donít come cheap. However, depending on how much the lost emails are worth to you, you might consider it a bargain after all.
Finally, should you ever need to reduce the size of your files, you can compress them:
