Improvements and fixes

  • Fixes the following issues:
    • In rare situations, the Office synchronization task scheduler cannot catch and handle a specific error condition that causes an Office 2013 application to crash.
    • When you try to synchronize a document library by using OneDrive for Business, the groove.exe process crashes.
    • When you use an older version of OneDrive for Business, OneDrive for Business (groove.exe) may crash.
    • When you use an Office 2013 application to open files from a OneDrive for Business folder or a SharePoint Server 2013 site, the Office 2013 application may crash if the device that stores files do not have sufficient disk space.
    • When you cancel the download of a file that is in the pending download situation in OneDrive for Business, the file is not deleted as expected.
    • When you use OneDrive or OneDrive for Business to synchronize a file, a conflict still appears if the conflict is resolved by a third-party application.
    • The WebPath property is not returned as expected for group folders of OneDrive. In this situation, file changes are in an error state, and cannot be uploaded.
  • Introduces a registry key to control the mapping feature between a local file and a server file for Microsoft OneDrive and Microsoft OneDrive for Business.
