A new view is being deployed on OneDrive for Business to help you identify all content you have shared.
This new view is simply called Shared by me (as you would imagine 
)
To access this view, logon to your OneDrive for Business space using a web browser and reach the Shared view
On top you will see 2 views: Shared with me and Shared by me
Then, you can directly manage the access by selecting the shared content and click on the Manage access button
