Microsoft has yet to announce officially the launch of Office 365, but the pricing details for the company’s Cloud productivity suite are already live. There are different flavors of Office 365, tailored to customer segments with different needs, and priced accordingly.

Based on the size of their organization, companies can opt either for Office 365 for professionals and small businesses or for Office 365 for midsize businesses and enterprises.

The Office 365 for professionals and small businesses (Plan P) is the most affordable, at just $6 per user per month.

According to Microsoft, the $6 per month version of Office 365 includes:

“- Email, calendar, contacts, personal archive, and 25 GB mailbox storage with 35 MB attachments with Exchange Online;

- Office Web Apps and SharePoint Online

- instant messaging, presence, online meetings, and PC-to-PC audio/video calls with Lync Online

- premium antivirus and anti-spam filtering with Microsoft Forefront Online Protection for Exchange.”

Larger companies will be able to choose from a number of enterprise plans, no less than four, superseding one another in terms of the services offered.

E1 which costs $10 per user per month comes with “advanced administration capabilities, Active Directory integration and 24/7 support; Exchange Online; SharePoint Online; Lync Online; Microsoft Forefront Online Protection for Exchange; and license rights to access on-premises deployment of Exchange Server, SharePoint Server and Lync Server.”
