Hosted Exchange gives small businesses all of the benefits of an enterprise grade e-mail solution. These benefits include the syncing of all e-mail, calendar, contacts, and tasks across all of your devices. When e-mail is read on one device, it shows up as read on all devices. This solution also gives you the ability to create shared calendars so all employees can see the schedule of each employee in real time. This feature enables admin staff to add, edit, or remove items from employee schedules. The e-mail is also hosted on a redundant server architecture so you no longer need to worry about backing up your outlook files on your computer. This service can cost as little as $4/month.
