Microsoft Corp. today announced that, effective September 2008, Jeff Raikes, president of the Microsoft Business Division (MBD), will retire from the company following a nine-month transition to ensure a smooth transfer of his daily responsibilities and management of the division.

The company also announced that Stephen Elop, formerly chief operating officer (COO) at Juniper Networks Inc., has been hired as president of the Microsoft Business Division. Elop will start at Microsoft at the end of January and assume responsibility for the Information Worker, Microsoft Business Solutions and Unified Communications businesses -- all previously led by Raikes. Bob Muglia, senior vice president of the Server and Tools Business, will move to report directly to Microsoft CEO Steve Ballmer and continue managing the Server and Tools Business. Between now and his retirement, Raikes will continue to serve as a member of the company's senior leadership team responsible for developing and guiding Microsoft's core business strategy.

"Since 1981, I've had an incredible journey here at Microsoft. Given the success of our business and the depth of leadership we have in place today, the time is right for me to leave the MBD business in the capable hands of our new generation of leaders," Raikes said.
