Add a folder to the folder list

This example shows how to use the Add(String, Object) method to add a folder to the Outlook folder list.

Example

In the following code example, AddMyNewFolder calls the Add method of the Folders collection to add a Folder object that represents a folder called “My New Folder” to the Inbox in the Outlook folder list. “My New Folder” is then displayed.

If you use Visual Studio to test this code example, you must first add a reference to the Microsoft Outlook 15.0 Object Library component and specify the Outlook variable when you import the Microsoft.Office.Interop.Outlook namespace. The using statement must not occur directly before the functions in the code example but must be added before the public Class declaration. The following line of code shows how to do the import and assignment in C#.

using Outlook = Microsoft.Office.Interop.Outlook;

private void AddMyNewFolder()
{
    Outlook.Folder folder =
        Application.Session.GetDefaultFolder(
        Outlook.OlDefaultFolders.olFolderInbox)
        as Outlook.Folder;
    Outlook.Folders folders = folder.Folders;
    try
    {
        Outlook.Folder newFolder = folders.Add(
            "My New Folder", Type.Missing)
            as Outlook.Folder;
        newFolder.Display();
    }
    catch
    {
        MessageBox.Show(
            "Could not add 'My New Folder'",
            "Add Folder",
            MessageBoxButtons.OK,
            MessageBoxIcon.Error);
    }
}
