I think your only chance at this point will be the extract from disk feature
of DBXpress (see www.oehelp.com/DBXpress/)

For the future see points 2 and 3 here (www.oehelp.com/OETips.aspx) and
backup frequently.

Hi,

My Sent Mail Items has reach 2GB Limit and I have move some mails to
another
folder. Then I choose to compress the Sent Mail Items Folder. However,
most
of my e-mail lost after the compression. I wonder what happens to my
mails?Thank you.

Almost forgot, during the compression, a warning message like "outlook
express is using the file" has prompted on the screen.
