The Radicati Group Inc. on Thursday issued a report indicating that IBM’s e-mail product strategy—with its converging Notes/Domino and Workplace roadmaps—will lead to the company losing share in the corporate e-mail market over the next four years.

The report says that Lotus Domino now has an installed base of 85.9 million mailboxes, representing 24 percent of the market. The fledgling Lotus Workplace product is expected to have 3.7 million mailboxes by the end of this year, or 1 percent of the market. By 2008, Workplace’s share of the e-mail server market is expected to increase to 6 percent, or 38.4 million mailboxes. However, Domino’s share is expected to fall to just 11 percent, or 76.8 million mailboxes, according to the Palo Alto, Calif., consulting and market research firm.

The report describes IBM’s messaging software strategy as “ambitious, yet confusing.”
