I have installed Duplicati for first time, and I have finished a successful setup. I’ve done test connection to the server and everything works fine. But later, at the time of running backup I have received this error message.
Fatal error
Microsoft.SharePoint.Client.ServerUnauthorizedAccessException: Access denied. You do not have the necessary permission to perform this action or have access to this resource.

How can I solve this?
