Today, Office 365 hit general availability in 40 countries, with more to come. The launch was accompanied by a Live Webcast with Steve Ballmer.

Microsoft has is offering Office 365, with accompanying plans, for:

• Professionals and Small Businesses;
• Midsize and Enterprise;
• Education (formerly known as live@edu).

More information on the Office 365 service descriptions, plans and pricing, check here. Note that the information – and pricing – is localized and may vary from country to country. Tony Redmond wrote an interesting article on this, as well as some other interesting facts, here.

Also, and I can’t emphasize this enough, be aware of the limitations of any cloud solution. Not only will the provider set the terms and conditions to which you’ll be subjected, you’ll also need to plan for potential business continuity risks, such as downtime of the service or the patriot act. More on the latter here.
