What does "Exchange ActiveSync" do?

Exchange ActiveSync is designed specifically to facilitate the synchronization of emails, contacts, and calendar information between mobile devices and Microsoft Exchange Server. This protocol allows users to access their Exchange mailbox data seamlessly on their smartphones and tablets, ensuring that any changes made on one device, such as sending an email or editing a calendar event, are reflected across all devices.

By using Exchange ActiveSync, organizations can enhance the mobile experience of their users, making it easier for them to stay connected and productive while on the go. The synchronization capabilities extend not only to emails but also to tasks and notes, providing a comprehensive mobile messaging and information management solution.

This focus on mobile synchronization is what differentiates Exchange ActiveSync from the other options, which do not capture the primary function of this protocol.
