iPhone and ActiveSync / Exchange

The article below relates to the present state of the iPhone, but the link will take you to the proposed changes that will be out this summer. I intend to follow and update you on all the Microsoft compatibility with iPhone issues. You can subscribe to this blog here by RSS or email, if you’d like, or check back periodically.

Since I was so curious about this topic (being a Smartphone user) I figured I’d post some of my research on what the “Exchange” account setup feature does provide on the iPhone, and what’s missing from a normal ActiveSync-enabled device.

When one only has a POP/IMAP account, calendar, contacts, and tasks can only synchronize when connected via a cable (or through third party wireless synchronization software that is installed on one’s desktop).
