Microsoft adding more users than IBM in e-mail battle, report shows

摘要

Microsoft is growing faster and gaining more users than IBM in terms of e-mail and calendaring tools, but the two vendors are near equals when it comes to customer dissatisfaction, according to a new report from Gartner. The report on e-mail seat share also shows that the two vendors appear to be in a deadlock on stealing accounts from each other's customer base regardless of the defection hype the two have perpetuated over the years; and that commodity e-mail providers have the potential to grab seats, mainly at the expense of Microsoft, over the coming years.
