Former Microsoft CIO Jim DuBois Microsoft Microsoft's chief information officer, Jim DuBois, has left the company, reports GeekWire.

DuBois had been with Microsoft since 1993, and was named its CIO in 2013. In that role, DuBois oversaw Microsoft's internal IT organization.

Earlier this week, Microsoft announced a massive reorganization of its sales efforts to focus on cloud computing. On Thursday, Microsoft announced that these changes would result in thousands of layoffs. It's unclear if DuBois' departure was linked to these changes.

Kurt DelBene, Microsoft's head of corporate strategy, will take on DuBois' responsibilities. DelBene is another long-time Microsoft veteran, save for a stint at the Obama administration where he was appointed to lead Healthcare.gov, the official portal for healthcare services under the Affordable Care Act (ACA).

DelBene won't be taking the title of CIO, but will still oversee Microsoft's IT department. DelBene will instead take on a new title of Chief Digital Officer, helping oversee Microsoft's efforts to modernize its internal IT practices.
