Recently we faced an issue when a user try to sync with SharePoint using OneDrive.
After googling, I found the OneDrive logs are present in the SPW folder https://community.office365.com/en-us/f/154/t/279832
But It is .ETL.Z format.
I tried to open with Event Viewer, But it doesn't works.
How to open .etl.z file? Its 'OneDrive for Business' log files
