As you know, sharing on SharePoint Online and OneDrive for Business is a quite easy capability (especially when sharing with your colleagues).
That said, it was quite difficult for end-users to have a clear view on what and how their content stored on OneDrive for Business was shared.
This is no longer a problem as they have the ability to get a report on how their content is being shared.
To access the report logon to your OneDrive for Business space (https://<your tenant>-my.sharepoint.com) and access the OneDrive Settings menu
Then go to the More Settings and click on Run Sharing Report to get a CSV file
You then define where the report will be saved (only in your OneDrive, you can not save it locally – but this will be as you are using the OneDrive client to sync on your device 
)
Once the report is ready you will receive a notification email to let you and then you can check it
NOTE the Open link does not open the report but the location where the report has been saved
The report will looks like the below screenshot, showing the item(s) being shared, with who, their permission and how it has been shared (group or individual sharing)
