Sharepoint Online (Office 365): your client does not support opening this list with Windows Explorer

Aug 19

  • Add https://*.sharepoint.com to Local Intranet Sites in the Internet Explorer (Internet Options -> Security -> Local intranet -> Sites -> Advanced -> Add). Without this prerequisite, nothing will work.
  • Make sure the Web Client Service is not disabled (run services.msc and check)
  • Opening a document library with Explorer only works with the 32-bit version of the Internet Explorer 10. So, on a x64 box, start "C:\Program Files (x86)\Internet Explorer\iexplore.exe" explicitly and pin that to your taskbar instead of whatever was there before. 
  • Assuming you have Office installed, try opening an Office document first. If this succeeds, you can most likely open the library with Windows Explorer subsequently.
  •  If none of the above helps, change the following registry setting


    to the value of 2 (default is 1).
