Outlook Error: Unable to Open Your Default E-mail Folders File

MS Outlook’s PST file is quite susceptible to corruption in several situations like improper system shutdown, virus invasions, abrupt termination of Outlook application, oversized PST file, internal hardware or software issues and so on. Due to this abnormal conditions Outlook users often loose their crucial data and the application itself behaves strangely. Even sometimes the PST file of Outlook displays its file size to 0KB which is really alarming. In such scenarios it is important to restore the lost PST data by using any appropriate or valid backup or in case it is unavailable then Outlook’s inbuilt utility Scanpst.exe or Inbox Repair tool need to be used. But if Scanpst.exe also fails to fix this issue then you need to go for advanced Outlook PST Repair software.

Let’s consider a practical scenario, where you use Windows XP based system and to resolve some system related corruption, you executed CHKDSK utility which fails due to some reasons. After that when you tried to open MS Outlook it does not open and throws an error message similar to –

"Unable to open your default e-mail folders".

Soon after the error message, when you checked the PST file it turned out to be deflated with file size of 0KB.

The root cause of the error message thus flashed and the PST file which is displaying its size to 0KB is due to the PST corruption and the failure of CHKDSK utility.

So, in order to resolve this issue, you need to use Scanpst.exe tool but make sure that you backup your PST file before using this tool. Use can locate this tool at –

"C:/Program Files/Common Files/System/MSMAPI/1033"
