How to Recover Outlook Data If the PST File Becomes 0 Byte

Many people are asking for help because that their PST files become 0 byte. That is to say, their Outlook data is inaccessible. Now let’s explore how to recover the data effectively.

For some reasons, I need to scan and fix the errors in my system drive. When I ran chkdsk in Command Prompt, I was asked if I would like to schedule the disk check the next time system restarts. I input “Y” and rebooted my computer at once. Then when it started, chkdsk worked automatically. After this process, my computer started normally. But later when I launched Outlook, I received an error that my Outlook file is not a personal folder file. Next I located the PST file in Windows Explorer. Unexpectedly the file becomes 0 byte! The above mentioned scenario is my practical experience. And the followings are my resolutions for your reference.
