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

1 Answer 1


Please take a look at the following question I recently asked on MS site: OneDrive for Business log files.

Looks like despite of *.etl extension this files are packed with specific archiver which can be opened by MS staff only (but I haven't done deeper research)
