When setting up Known Folder Move in OneDrive for Business, you receive the following error message:
An unknown error occurred. (Error code: 0x80070005)
This is caused by a group policy preventing the the feature from running.
Use gpedit.exe, modify a Group Policy.
Navigate to User Configuration > Administrative Templates > Desktop > Prohibit User from manually redirecting Profile Folders.
Set the value to “Not Configured.”
It is possible your company’s administrators do not want you to configure this feature if the Group Policy is enabled. Your administrator may also elect to continue to enforce the policy even if you manually override it.
