Email deletions
 

Unlike Verizon, AT&T email push options seems to delete the email on your home PC server if you delete it off your PDA. Any idea how to stop that from happening?

Yeah, don't delete it off your phone. Depending upon how many days you have it set to download data (the default is the past 3 days), you'll only see that much email. If you don't want a lot of emails on your phone, set that number of days lower by going to Tools > Options in ActiveSync, highlight the Email under your exchange server, and click Settings. You'll see the place in the subsequent panel where you can change the days to download.
