First published on the Microsoft Office 365 blog, July 2011. Some links have been changed to point to the UK website. Prices are correct for the UK.

We are one week post the Office 365 launch and are flattered and excited to see all the excitement on the web about our new service. Several customers have shared with us how Office 365 is already boosting productivity with estimated cost savings of up to 50%! I wanted to continue our top questions series, to answer some of the great questions as we’ve been receiving on getting started with Office 365 through Facebook, Twitter and right here on the Office 365 blog. Enjoy!

Q1: What is Office 365? Is it just “Office in the cloud”? Where can I learn more?

Office 365 is that and so much more! Office 365 combines the power of Office desktop apps with enterprise-grade email, shared documents, instant messaging, and video and web conferencing (Exchange Online, SharePoint Online, and Lync Online) in an always-up-to-date cloud service that is backed by Microsoft and some of the best partners in the world. Further, Office 365 bring access to the Office Web Apps, which enable you to view, share and edit your Microsoft Office documents on the web with virtually any device connected to the internet. These services combine to provide you with the most comprehensive productivity solution for your business needs. Watch our professionals and small business or enterprise demos to get a taste of these services all working together.

Q2: Which Office 365 plan is right for my business? Where can I find pricing information on these plans? Can I switch between the two later on?

Office 365 offers plans tailored to meet your business’s needs, whether you are a new business, an established organisation, a small office or a multi-national enterprise. Office 365 for professionals and small businesses (Plan P) is designed for organisations with fewer than 25 employees and is just £4 per user per month, while Office 365 for midsize businesses and enterprises (Plans E1-E4 and K1-K2) provides larger organisations with the tools they want with the IT control, security and reliability you expect from Microsoft in a range of plans from £2.60 (K1) - £17.75 (E4). And if you are a smaller org with technical know-how, you’ll be happy to know that there are no minimum seat requirements for the enterprise plans, it works for orgs of one to thousands. The small business plan (P1) is capped at 50 users and cannot be transitioned later on. To find which is right for you, take a look at our professionals and small businesses and midsize businesses and enterprises placemats to compare the included features. For a more in depth analysis and feature list, see our Office 365 service descriptions.
