Study: Microsoft still leads in e-mail

In 2005, Microsoft led the e-mail software market and is expected to continue to do so, according to a report from Radicati.

Microsoft will stay at the top of the growing corporate email market, thanks in part to its software's new wireless push capabilities, according to a new report from The Radicati Group.

The study found that Exchange, Microsoft's email platform, currently had 23 million more seats than Lotus Domino, IBM's email platform. The addition to Exchange of push wireless email, which is part of the Service Pack 2 upgrade, should keep driving users to Microsoft in the future, Radicati said.

Spam will continue to be a problem regardless of which platform enterprises use. In 2005, spam traffic totalled 91 billion messages per day, the report found.

By 2009, spam was expected to reach 228 billion messages per day, Radicati said.

Messaging software, including email software used by enterprises and software used for hosted email services, would generate $US3.6 billion in 2009, up from $US2.5 billion in 2005, the report said.
