Uploading file into Share Point online with a outlook live id using C#

HI,

I need to upload file into share point online (2013) using C# with a live id test@outlook.com. I am using the below code                                  

    string siteUrl = "https://microsoft.sharepoint.com/xxx/yyyy";
            string filePath = Console.ReadLine();

            ClientContext context = new ClientContext(siteUrl);

            SecureString passWord = new SecureString();

            foreach (var c in "password") passWord.AppendChar(c);
            context.Credentials = new SharePointOnlineCredentials("test@outlook.com", passWord);

            Web site = context.Web;

            //Get the required RootFolder
            string barRootFolderRelativeUrl = "Shared Documents/abc/Main";
            Folder barFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);

            Folder currentRunFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);
            FileCreationInformation newFile = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(filePath), Url = System.IO.Path.GetFileName(filePath), Overwrite = true };
            currentRunFolder.Files.Add(newFile);
            currentRunFolder.Update();

            context.ExecuteQuery(); 

But I am getting below exception:

An unhandled exception of type 'Microsoft.SharePoint.Client.IdcrlException' occurred in Microsoft.SharePoint.Client.Runtime.dll

Additional information: The Login server cannot issue the requested compact encrypted ticket because a Data Encryption Key (DEK) has not been uploaded to the site.

Please help me to resolve this.

Thanks,

Trinadh
