Nicole Dezen has been appointed as chief partner officer and global partner solutions corporate vice president.
Dezen will report to Nick Parker, who previously held the title, and has been promoted to industry and partner sales president.
"As a long-time Microsoft employee and someone who has deep ties in our sales and partner organisations, I have always been motivated by the opportunities for growth and innovation that our partner ecosystem presents," Dezen writes in a LinkedIn post.
"I am both humbled and thrilled to take on the new designation of [chief partner officer] for Microsoft. This is a new title and one that speaks to the enormous opportunity we believe we can unlock in concert with partners around the world.
"The best way for me to describe my commitment is to say that I will be dedicated to doing everything possible to help partners build successful businesses with Microsoft.
"Working with them to create differentiated solutions; making it easier, more seamless and more profitable to do business on Microsoft Cloud; unlocking hidden potential through co-selling and strategic partnerships; and evolving how we engage with partners, so they can spend more energy with customers."
