OneDrive for Business sync client issue
After a recent Microsoft update, the OneDrive for Business sync client is experiencing issues. Users that have mounted OneDrive for Business on their local computers will be unable to create or save changes to the documents stored there. Until the issue is resolved by Microsoft, a temporary workaround is to create and edit Office documents in a web browser. To do this, log in with your Caltech credentials at http://caltech.onedrive.com to create or edit documents.
