Richard Dunmall, Microsoft Advertising’s VP for the Greater Asia Pacific and Americas, will take on a new global role managing key clients and agency relationships.
As vice president of global agencies and accounts, Dunmall will take overall responsibility for driving revenue with the company's largest advertisers and agency partners globally.
Microsoft Advertising will replace Dunmall's role in Asia and a search is currently underway.
"With the existing leadership team in place of Kerry McCabe, Todd Paris and Kenneth Andrew, a smooth transition is expected," a company spokesperson said.
Dunmall is expected to re-locate from Hong Kong to New York but currently there is no date set. In the meantime he will split his time in both markets.
In his new role he reports directly to Microsoft Advertising's global corporate vice president, Carolyn Everson.
Everson said Dunmall was a natural choice for this role, bringing expertise from the world's mature and emerging markets.
"The Asia region is critically important to the global advertising industry, and to digital," Dunmall said.
"We've got a strong leadership team in Asia that is consistently pushing the boundaries to deliver advertising solutions for our agencies and clients. With their continued support, I am confident that Microsoft Advertising's business globally, and here in Asia, will continue to grow and produce fantastic results for our customers."
