The Advanced service is ideal for customers looking for a means to easily collaborate with co-workers with its ability to readily share any resource (mailboxes, calendars, address books, task lists) with others. It's also perfect for customers that are on the go & need quick and convenient access to their mailboxes, calendars, and address books from wherever they are, using their phone or tablet. Available as an add-on option, the Advanced service tier also supports archiving & legal discovery features for corporate & government compliance needs.

The Basic service tier, available for $1.50 per month per mailbox, is ideal for customers looking for a robust email service who may not need all of the features of the Advanced service tier, and rather value flexible options for accessing their email accounts from any computer, phone, or tablet. Many customers whom start with the Basic service tier tend to grow into the Advanced service tier, as their needs increase over time, offering an easy, no-hassle upgrade path which can be done within minutes.
