The Radicati Group Inc. on Thursday issued a report indicating that IBMs 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, Workplaces share of the e-mail server market is expected to increase to 6 percent, or 38.4 million mailboxes. However, Dominos 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 IBMs messaging software strategy as "ambitious, yet confusing." Ferris Research Inc., in a report issued this week, likewise said IBMs Domino roadmap still needs clarification.
Radicati said that 71 percent of IBMs corporate-messaging installed base is on Domino 6.x, compared with only 57 percent of Microsoft Corp. customers that have moved up to Exchange 2000 or Exchange 2003.
Total worldwide mailboxes are expected to hit 988 million by the end of this year, with 366 million of those being in-sourced corporate mailboxes, the report says.
