Data Execution Prevention is a security feature in Windows that prevents the
files it monitors from running if they could damage the computer. That would
include corrupted files or malware (details in Help and Support). The
default settings for DEP only includes essential Windows programs and
services.

As I understand it, Windows Mail stores messages as individual email/news
files rather than using the database format that OE used. You might have one
or more corrupted files causing the compression process to fail. If you
know which folder the compression routine is working on when the error
occurs that could narrow down the problem area. Other than that you could
try exporting the emails from each folder one at a time to a backup folder,
delete the original folder contents and try running compression again to see
if it still has the error.

Windows mail keeps trying to compact the the files when I close the
program.
It keeps trying and I get errors. How is this fixed? It's the most
annoying thing as it doesn't
quit, if I click OK - I get another error. How do I get it to compact the
news/mail
files? Never had this problem with OE

I used this www.oehelp.com/WMUtil/ to compact and repair the database - it
said it compressed it, but did not. WMail is still trying to compess the
data base every time I close the program. How is this fixed once and for
all? I'm also getting a little window pop up from the bottom bar saying
"Data Execution Prevention closed Windows?"
What the hell is "Data Execution Prevention?"
