Microsoft Exchange is an enterprise-level email service that is geared towards
email intensive companies, with synchronization across all devices and premium
spam and virus filtering. With Exchange, all of your email messages are synchronize
over the air between your desktop, mobile device and web portal.
This includes incoming, outgoing and saved emails within folders, and are all
stored on the server indefinitely with unlimited storage space and back up.
This prevents any vulnerabilities in losing your email history should your local
computer crash or get a virus, and allows all your email history to be available
to you from anywhere. Not only do your emails synchronize, but so do your contacts,
calendars and memos, allowing you to enter a contact on your mobile phone and
instantly have that contact in your Outlook when you get back to your office.
