How to make work Skype Meeting on custom Outlook appointment add-in? RRS feed

  • Question

  • Hello Everyone,

    I received task to develop custom add-in for my management (I'm not Office developer). In order to do it I have added ribbon and button with event handler:

    public partial class Ribbon1
            private void Ribbon1_Load(object sender, RibbonUIEventArgs e)
            private void button1_Click(object sender, RibbonControlEventArgs e)
                    Microsoft.Office.Interop.Outlook.Application outlookApplication = new Microsoft.Office.Interop.Outlook.Application();
                    Microsoft.Office.Interop.Outlook.AppointmentItem newAppointment =
                    newAppointment.Start = DateTime.Now.AddHours(2);
                    newAppointment.End = DateTime.Now.AddHours(3);
                    newAppointment.Location = "ConferenceRoom #2345";
                    newAppointment.Body =
                        "We will discuss progress on the group project.";
                    newAppointment.AllDayEvent = false;
                    newAppointment.Subject = "Group Project";
                    newAppointment.Recipients.Add("Roger Harui");
                    Outlook.Recipients sentTo = newAppointment.Recipients;
                    Outlook.Recipient sentInvite = null;
                    sentInvite = sentTo.Add("Holly Holt");
                    sentInvite.Type = (int)Outlook.OlMeetingRecipientType
                    sentInvite = sentTo.Add("David Junca ");
                    sentInvite.Type = (int)Outlook.OlMeetingRecipientType
                catch (Exception ex)
                    MessageBox.Show("The following error occurred: " + ex.Message);

    Everything works fine until I run this add-in and I want to click "Skype Meeting". Nothing really happens then. Moreover I'm not able to go back to my main Outlook window. My custom appointment is "freezing" and doesn't allow to perform any actions outside.

    Do you have any ideas on how to overcome these two issues?

    Thanks in advance for any suggestions.

  • Hello Mateusz,

    First of all, there is no need to create a new instance of the Application class. Instead, use the Globals.ThisAddin.Application property. See Program VSTO Add-ins for more information.

    There is no reason to display a new appointment modally. So, I'd suggest passing false to the Display method instead:
