Microsoft began selling last month the consumer versions of the new Office, and plans to announce details of the business versions of the suite Wednesday.
Office 365 for business, introduced in mid-2011, has options that range from an email-only version with Exchange Online to jam-packed bundles that also include SharePoint Online, Lync Online and the full-featured Office productivity applications suite with Word, Excel, PowerPoint and others.
Maintaining the relevance, popularity and viability of the Office stack is critical for Microsoft, since those products represent a major portion of the company's revenue. However, competition has intensified in recent years from a broad variety of rivals including Google, IBM and Cisco.
In Microsoft's second fiscal quarter, ended Dec. 31, the Business Division, which includes the Office suite, reported US$5.69 billion in revenue, down 10 percent year on year.
