Helio Ocean users can now add Microsoft Exchange accounts to the long list of email services the device is compatible with. The carrier announced Mail for Microsoft Exchange today, an application that adds synchronization of Exchange Mail, Contacts and Appointments to the Ocean. Helio is offering a free 60 beta period for the application, but it will cost $10 per month to all-in subscribers after the trial is over. Users of this new application will soon get access to a viewer application for Microsoft Office and PDF files as well.
