How to Create a Custom Folder for a Custom Message Class with a Custom Form Region RRS feed

  • Question

  • I have searched everywhere for this, but everything I find is about creating the custom form region which I can already do.

    What I want is to programmatically create a "Widgets" folder in the navigation pane that works similar to the "Inbox" folder. I want that folder to only store items with a custom message class of "IPM.Widget" which will open with the form region I've already created. I can find samples on how to add the folder but not on how to configure the folder specifically for my message class. Can anybody point me in the right direction?

  • Hi David,

    As far as I know, you could achieve this programmatically. Here are the steps.

    1. Use Newmail event when receiving a mail, then check the mail's class.
       Code block:

            Outlook.Application app;
            Outlook.Items items;
            Outlook.NameSpace ns;
            Outlook.MAPIFolder inbox;
            private void ThisAddIn_Startup(object sender, System.EventArgs e)
            {            
                app = this.Application;
                ns = this.Application.Session;
                inbox = ns.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
                items = inbox.Items;
                app.NewMail += new Microsoft.Office.Interop.Outlook.ApplicationEvents_11_NewMailEventHandler(app_NewMail);
            }

    2. In the app_NewMail method, check the mail's class and then move this mail to the "Widgets" folder.
       Code block:

    void app_NewMail()
            {
                Outlook.MailItem item;
                item= items.GetLast() as Outlook.MailItem;
                MessageBox.Show(item.Subject.ToString());
                if (item.MessageClass == "IPM.Widget")
                {
                    item.Move(DestFldr); //Move(Microsoft.Office.Interop.Outlook.MAPIFolder DestFldr)
                }
            }

    Since I don't know where is the "Widgets" folder you want to create, I write code snippet as below. You can make some changes to get the folder named DestFldr.
      Code block:

    foreach (Outlook.MAPIFolder rootFolder in this.Application.Session.Folders)
                {
                    if (rootFolder.Name == "Local Main Mailbox")
                        foreach (Outlook.MAPIFolder folder in rootFolder.Folders)
                        {
                            if (folder.Name == "testss")
                                foreach (Outlook.MAPIFolder folder1 in folder.Folders)
                                    if (folder1.Name == "tests")
                                        foreach (Outlook.MAPIFolder folder2 in folder1.Folders)
                                            if (folder2.Name == "test")
                                            {
                                             .....
                                            }
                        }
                }
