The definitions of active sync according to Wikipedia is “Active Sync allows a mobile device to be synchronized with either a desktop PC or a server running a compatible software product”.
The active sync really allows you to work with your mails, contacts, tasks, and calendar on virtually any device. All data is stored in the cloud and available from anywhere and synchronized the whole time. The above means you have your whole office virtualized and available on your phone, tablet or desktop (running outlook or other mail client software).
Active sync is ideal for people who need access to this data 24/7 without the worry of things getting lost on devices. Active sync is available in our advanced hosting packages.
