pst file size 0kb, lost?

I have also experienced this issue: " I opened Outlook 2003 this morning and received an error message that the set of folders could not be expanded.  So I closed the .pst file and then tried to reopen it.  I then received an error that outlook did not recognize the file type.  I then went to where the file is located and to my the suprise the file size is now 0Kb.  I last successfully opend it on Thursday last week and it was working fine.  I imagine it was aproaching 2Gb.  Any chance this can be repaired?   Any suggestions would be appreciated."  I have tried scanpst.exe without success, it does not recognize the pst file when I select it.  I have tried some recovery s/w for deleted/corrupted files on the hard-drive without a loss on this, any help would be appreciated.

Hello dsteven2,

Unhide hidden files. In Windows XP, open Windows Explorer or any folder.  Click on Tools > Folders Options > View. Check "Show hidden files and folders".  If you want to see system files as well, unclick Hide protected operating system files.   Click OK.

Then perform Windows search for *.pst.  You may have a backup pst file or archive.pst

You can try to recover deleted files with GetDataBack     

Hope this helps!

2 gig is not the limit for Outlook 2003 format file.  The limit is 20 GB.
why not recover the system to your most recent restore point of 2-3 days ago, or just before this happened.  Then with a valid PST file, copy the thing to another location for safe keeping.  Then proceed again and see what happens.  Before you restore, if you installed any programs on C since, you might want to note them down, they will need reinstalling.

This was helpful as an action to take in working through this issue but did not help resolve my problem in the end.  None of the offered solutions did, although they were all helpful.  I appreciate all the feedback.
