Microsoft CEO Satya Nadella, as revealed in an internal e-mail shared by Microsoft, has announced three leadership changes within the company.

“I want to highlight three announcements about how we’re continuing to evolve and tune our organization for maximum focus and impact,” he wrote in the e-mail.

Nadella announced that Scott Guthrie, who has been acting leader for the Cloud and Enterprise division for the past two months, has been promoted to executive vice president.

“As a leader, Scott has shown incredible energy and insight into how we create technology that others can build on, and which can be built on what others have created,” Nadella wrote.

Phil Spencer, who most recently was the chief of Microsoft Studios, has taken a new role leading Xbox. Spencer will report to Terry Myerson, executive vice president of Microsoft’s Operating Systems Group. In Spencer’s new position, he will lead Xbox, Xbox Live, Xbox Music and Xbox Video teams as well as Microsoft Studios.

“Combining all our software, gaming and content assets across the Xbox team under a single leader and aligning with the [Operating Systems Group] team will help ensure we continue to do great work across the Xbox business, and bring more of the magic of Xbox to all form factors, including tablets, PCs and phones,” Nadella wrote.

Lastly, the man who was once rumored to be the new Microsoft CEO, Stephen Elop, will become Microsoft’s executive vice president of the Devices Group. The Nokia CEO’s position will be effective with the close of the Nokia deal. The Nokia acquisition is expected to take place by the end of April.

“I look forward to working with Stephen as a key member of the senior leadership team and welcoming the Nokia Devices and Services employees to the Microsoft family,” wrote Nadella. “The mobile capabilities, hardware design expertise, and world-class manufacturing and supply chain operations they bring will help us drive innovations in devices to delight our customers.”

Elop will report to Nadella as well as work closely with Spencer and Myerson on Xbox.
