The Radicati Group have released another one of their in-depth studies. “Microsoft Exchange Server and Outlook Market Analysis, 2011-2022,” provides an in-depth analysis of the penetration of the Microsoft Exchange Server messaging platform and Microsoft Outlook email client, in both the On-Premises and Hosted Messaging and Collaboration markets.

According to the report, Microsoft Exchange Server will have a worldwide installed base of over 360 million on-premises and hosted mailboxes by year-end 2011. On-premises deployments account for around three quarters of the world’s userbase.

The study doesn’t just stick to Exchange, however. It also doles out extensive coverage of all leading Microsoft Email and Collaboration solutions, including: Business Productivity Online Suite (BPOS), Microsoft Office 365, Microsoft Hosted Exchange, Microsoft Outlook Web App (OWA), and Windows Live Hotmail.
