Microsoft is rolling out three new pricing options for its cloud-based Office 365 services aimed at small and mid-sized companies with up to 250 employees. The new plans are available today, and range from $5 to $12.50 per user per month with an annual contract. The cheapest package Microsoft will offer is called Office 365 Business Essentials, and as you might expect it offers a pretty bare bones experience for just $5 per user per month. It includes core services for email, calendar, Office Online, IM, video conferencing, cloud storage and file sharing, but no desktop apps.
