OneDrive error code 0x8004def7 can occur when OneDrive is not able to connect to the Microsoft servers. This can be caused by a number of things, such as an unstable internet connection, incorrect proxy settings, or a firewall that is blocking OneDrive. If you are seeing this error, we recommend checking your internet connection and proxy settings first. If those are not the issue, then try temporarily disabling your firewall to see if that allows OneDrive to connect.
