By doing so, he added himself to the increasing numbers of people making thousands in bug bounties.
Wesley Wineberg has blogged about his efforts on the Synack Labs website.
According to Microsoft, his work was celebrated between June and July 2015 and before.
However, the amount of the reward has not been listed by Microsoft.
Wineberg started his research by analysing how an attack on Hotmail, now known as Outlook.com, would start.
He said that there are problems with the OAuth authentication services.
After Wineberg alerted Microsoft regarding the issue, the Redmond company was quick to respond and fix the issue.
On August 23, Wineberg completed his proof of concept attack and reported it to Microsoft on August 25.
