Microsoft is clearing out one of its two Kendall Square offices, sending 300 sales and marketing employees to Burlington in a multi-year move that will begin later this year.

In a blog post Wednesday, Microsoft general manager Robert Davy said the sales, marketing and services group workers will move to a former Nokia office in Burlington.

Microsoft’s office at 255 Main Street in Cambridge, on the edge of the MIT campus, will be emptied once the lease expires in 2020, the company said. Microsoft first moved into that space in 2012.

The new Burlington office “places us in a centralized location close to Boston, but with easier access to all the surrounding states in our sales region,” Davy wrote. Microsoft also has branch offices in Hartford, Conn. and Rochester, NY.

About 450 employees in Microsoft’s research and development group will remain at 1 Memorial Drive in Cambridge, known as the New England Research and Development Center, or NERD.

The company also plans to renovate the 150,000 square-foot NERD Center to give employees more elbow room and space to add new hires.

Kendall Square has become a hotbed for biotech and pharmaceutical companies in recent years, which has helped raise rents and forced smaller tech startups into other areas of Boston and Cambridge.

Several West Coast tech companies also have branch offices in the neighborhood, including Google, Amazon, and Twitter. Homegrown tech companies such as Akamai and HubSpot also are headquartered around Kendall Square.
