PALO ALTO, CA--(Marketwire - December 1, 2008) - The latest study by The Radicati Group, Inc., "Messaging and Collaboration Market, 2008-2012," provides an in-depth analysis of the worldwide market for enterprise messaging and collaboration solutions and includes market trends, installed base and revenue market share by provider, four-year forecasts, as well as breakouts by region and business size.

Revenue in the corporate messaging and collaboration market continues to grow due to the expansion of existing customer accounts, addition of new business customers, migration to newer messaging software releases, as well as raising price points on premium solutions by messaging vendors.

This study forecasts solid growth in the messaging and collaboration market, as the number of insourced corporate mailboxes will increase from a worldwide installed base of 413 million to 494 million by year-end 2012. However, an increasing number of insourced mailboxes are also expected to migrate to hosted email solutions over the next four years.
