を行ってくださいあなたが唯一のカレンダーへの代理人アクセスを持っているとして、あなたはに予定を保存したいようです。

あなたのコードの作業を取得するためには、

service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, emailAddress); 

行を削除して、このようなSave方法に変更してください：

appointment.Save(new FolderId(WellKnownFolderName.Calendar, new Mailbox(emailAddress)), SendInvitationsMode.SendOnlyToAllAndSaveCopy);
