Hi ! I am struggling with a problem and I have no idea any more. I am writing an application in .NET(C#) which should be able to create appointments and update them using outlook automation. Everything worked well till a couple of days ago where I could not any more save an Outlook.Exception.AppointmentItem using its Save() method after having modify it (say its start date). The error I get is the following : "You do not have the authorization to move this item." [Microsoft Office Outlook --> System.Runtime.InteropServices.COMException : Vous n'avez pas les autorisations nécessaires pour déplacer cet élément.] à System.Windows.Forms.Control.MarshaledInvoke(Control caller, Delegate method, Object[] args, Boolean synchronous) à System.Windows.Forms.Control.Invoke(Delegate method, Object[] args) [...] This error appears only when Outlook is running while trying to save. If Outlook is closed (the visual application, not the process outlook.exe) I can save the AppointmentItem without any difficulty. I am sure it worked because I tested it 2 or 3 weeks ago. Do you point out the cause of that weird behaviour ? Thanks in advance for your help ! Guim
