After almost 25 years of service in Microsoft, Windows and Office executive Antoine Leblond is finally leaving the firm, according to a Re/code report cited by VentureBeat. Leblond, who was left out during reorganization in 2013, will depart on Monday, the report said.

Leblond told employees in an e-mail: "After almost 25 years, I've decided it's time for me to go out and see what the non-Microsoft world has to offer. Every single day I have had here has been amazing in its own way, and I will never look back on all of these years with anything but fondness, pride in what we've accomplished together, and a real appreciation for having been lucky enough to be part of so many awesome things. I am sad to leave all of you, but also incredibly excited for what comes next."

According to Re/code, Leblond worked in the Office department for 20 years with Windows head Steven Sinofsky. When the latter transferred to Windows, Leblond also moved to the unit and worked on Windows 8 cloud services and store, the report detailed.

Leblond is not the only left-out Microsoft executive who left the company. Jon DeVaan and Grant George had already left the company last year, the report added.
