Microsoft exams – Leon flying high The Corbel Blog Written by CorbelAdmin on 23rd April 2018. Our service desk engineer Leon took his latest Microsoft exam recenlty and by passing it makes him now a Microsoft Certified Solutions Expert in Productivity. The exam on ‘Designing and Deploying Microsoft Exchange Server 2016’ was “tough” but Leon passed with flying colours. He’s such a Microsoft Superman, he even took his exam in a Superman t-shirt too!
