The GetSharedDefaultFolder method of the Namespace class accepts two parameters: a Recipient object and the FolderType value.

The How to: Display a Shared Calendar of a Recipient article provides the following sample code in C#:

private void DisplayManagerCalendar()
{
    Outlook.AddressEntry addrEntry =
         Application.Session.CurrentUser.AddressEntry;
    if (addrEntry.Type == "EX")
    {
        Outlook.ExchangeUser manager =
        Application.Session.CurrentUser.
            AddressEntry.GetExchangeUser().GetExchangeUserManager();
        if (manager != null)
        {
            Outlook.Recipient recip =
                Application.Session.CreateRecipient(manager.Name);
            if (recip.Resolve())
            {
                try
                {
                    Outlook.Folder folder =
                       Application.Session.GetSharedDefaultFolder(
                          recip, Outlook.OlDefaultFolders.olFolderCalendar)
                       as Outlook.Folder;
                    folder.Display();
                }
                catch
                {
                    MessageBox.Show("Could not open manager's calendar.",
                       "GetSharedDefaultFolder Example",
                       MessageBoxButtons.OK,
                       MessageBoxIcon.Error);
                }
            }
        }
    }
}
