Thanks for the welcome.
I've actually been using the resource kit to do a monthly dump of stats, and then using the difference with the previous month to give monthly totals. Lately though management, as they always do, wants more, such as being able to specify a specific date range to get stats from, and that's where I ran into problems.
I had started looking at the hidden folders in the individual Exchange mailboxes and what's listed there, but was assuming these list the mail still present in the mailbox that was sent to the handheld, so hadn't pursued a way to programatically grab those, unless I'm wrong on that. Was having a hard time finding information on those also.
Anyway, will dig a bit deeper. Any suggestions are appreciated.
