Like then, there are a number of companies all trying to provide the same thing--this time, a way to bring together voice mail, email and other digital communication in the corporation. But, also like then, many of their products are one-off approaches that don't work well with others. So to make its mark in this market, Microsoft is hoping that it can do what it has done in the past--create key underlying software, and then convince the rest of the industry to build on top of its architecture.
