Re outlook Express Compression - csaba Aug 7, 2007
i encountered the same issue. this may help you with your problem:
first, search the folder with ".bak" extenscion (inbox.bak) usually you may see this on your recycle bin folder.
2nd, changed the ".bak" to ".dbx" (inbox.bak --> inbox.dbx)
3rd, copy the "inbox.dbx" to your OE's store folder.
note: make to backup first your outlook express email before doing this instruction..
