I have a 2210 using Activesync 3.7.1. I have the inbox set to sync the last 20 days. In the last few days, the inbox says it is syncing something like 480 mails, even though there are only a total of about 100 emails in the inbox on my PC. When it does this, it also uses almost all the memory on the 2210 and I get a warning that the memory is dangerously low. I can fix this either by doing a hot boot on the ipaq, or sometimes by simply removing one email from my PC inbox. Any ideas why it's syncing over 4 times the amount of mails in my inbox?
