Most of the Outlook users find it impossible to access PST after facing above problem because PST file becomes corrupted during file copy or move operation. You may now wonder how PST file get corrupted if moved from one storage media to another?

While doing so, it is recommended to keep Outlook closed or else the PST file might get corrupted.
Outlook PST file is mainly composed of two parts, file header and data part. File header contains information about the PST file like file size, file signature, compatibility etc. The PST file header is very sensitive so you should always be careful while using PST file. Any harm to PST file header could lead to loss of entire Outlook data. In above mentioned situation, header of the PST file might have corrupted as a result of not closing Outlook while copying. Therefore Microsoft is not able to recognize the file and reported error message that “Outlook is not a valid PST file”
