Get Latest Version then open Output to Source Control - Team Foundation

[blodgettb]

Why doesn't this VS2017 macro open Output window to "Source Control - Team Foundation" after it does "Get Latest Version (Recursive)" for my solution?

dte.ExecuteCommand("ClassViewContextMenus.ClassViewProject.SourceControl.TfsContextGetLatestVersion");
dte.ExecuteCommand("View.Output");
dte.Windows.Item("{34e76e81-ee4a-11d0-ae2e-00a0c90fffc3}").Activate();
dte.Commands.Raise("{1496a755-94de-11d0-8c3f-00c04fc2aae2}", 1627, null, null);
