Roslansky's departure was announced in an internal memo from Microsoft CEO Satya Nadella on Thursday. Roslansky was promoted to head of Office last year after serving as CEO of LinkedIn, and earlier this year he took control of Microsoft Teams as part of a broader reorganisation.
"Ryan leaves the organization in a strong position," Nadella wrote in the memo. "Over the past year, Ryan's team has done critical work bringing together the product, engineering, and design foundations that have made this next phase possible."
The departure comes a week after Microsoft announced a significant reorganisation that saw its Copilot AI assistant more deeply integrated into its core productivity suite. The leadership shake-up appears to be the latest in a series of executive changes as the company restructures its product divisions around artificial intelligence.
Microsoft has not yet announced who will succeed Roslansky or detailed the full scope of the organisational changes. The company is expected to provide more information in the coming days.
