More on emailing.
Another advantage of using an Exchange hosted account, or at least in the case of my experience on 4Smartphone, is that your email gets filtered through another level of spam blocking, this time server side. For some statistics, I had been getting 90+ spam emails a day (like the rest of the world), with about 15-20 falling into my inbox, and the rest getting sent to the Junk Mail folder via Rules in Outlook. Now on a hosted Exchange account, I receive maybe 15 pieces of spam a day, with 3 falling into my inbox, and these could just be coming from my other (non-Exchanged) accounts. That’s about an 80% decrease in spam! Good stuff.
As shown below, you can set your Windows Mobile device to store email only from a given period of time. Most people would want this set to one day because of the way we use our devices for emailing (which would be for reading a day’s worth of email and writing quick replies, etc), and also in order to save space (although as posted over at Smartphone Thoughts, there’s a registry hack that keenly allows you to save mail on a storage card). For the next option, I have no limit on email size since I’m storing only one day’s worth of email. Finally, I don’t allow attachments to come through, although you have the ability to download them when you read a message with an attachement.
The second screen shows the various folders that I am choosing to sync. When I installed the settings onto my device to connect to the 4Smartphone server, all of my folders appeared in Outlook mobile, like magic. The green arrow shows that I have four subfolders set to sync and not the inbox itself, because I have Rules on my desktop in Outlook to distribute various messages to their respective folders. What I find annoying is that if Outlook is closed on my primary computer (and thus Rules cannot be applied as message come in), all emails will go straight into the Inbox on your Smartphone until the Rules are ran (by starting up Outlook again).
