I had lost important emails during the compacting process and didn’t know how to find them or reopen them. Your product resolved the isssue (eventually).
However, you should explain to ludites like me that any BAK fliles can be renamed DBX. The most improtant file I wanted was named BAK (which I understand may have happened in the compacing process) and it took me a day of research to work out that I could change the file name and then apply your product to do the rest. Once I’d worked that out it worked like a treat!
