On Tuesday, Nov 24, Microsoft said that Lidell was "looking at a number of opportunities that will expand his career beyond being a CFO."
The company also informed that Liddell will be staying at Microsoft through Dec 31 to ensure a smooth transition.
The 51-year-old New Zealander has been the CFO of the company since 2005.
Lidell helped Microsoft through the rough waters of global economic slump by implementing a hectic cost cutting plan.
The software major has named 47-year-old Peter Klein as Liddell's successor. Klein, who began working for Microsoft in Feb 2001, is presently the chief financial officer of Microsoft's business division.
