Split from this thread.
I'm having a similar issues using the following script:
net use t: "https://tenant.sharepoint.com/MediaScreen/"
del t:\*.* /q
copy "S:\Media Screens\Current\*.*" t:\
net use t: /delete
Immediately after the net use I get "System error 224 has occurred."
We have actually added tenant.sharepoint.com to the "Local Intranet" and "Trusted Sites" in IE and set this as a group policy so all users should be the same. The users are auto logging in when they access via the browser.
What other options to we have to make this work consistently?
