BPOS includes the Web-hosted versions of the Exchange e-mail of Microsoft, the SharePoint collaboration, and also some other Office communication related apps, which are now costing at $10 for one user for a month, which is down from $15 per user for a month. Microsoft has also expanded hosted storage limit up to 25 GB for a user, which previously was 10 GB.

A year after the official launch of BPOS, it is being used by a million of the paid customers as announced by Microsoft Corporation. Chris Capossela who is the senior vice president of group of information worker product management at the Microsoft Corp., has told Computerworld that 70 percent of these users come from IBM Lotus Notes or the Novell GroupWise. This looks to be a wonderful figure as it means that they are getting some new businesses too, and are not only migrating existing business to cloud.
