I've installed Microsoft Fix It on Windows 8.1 but it has not done its job, now what?

Hi,

Since buying my new laptop and installing outlook, my emails have not been sending and has given the code of 0x8004210b indicating that the server timed out. I have researched this and from information found downloaded ms fix it.

Of course I now realise ms fix it on 8.1 does not work so I have two questions:-

Where do I find the Microsoft files relating to Ms fixit that I can delete (I have looked but cannot find)?

And What can I do now to rectify this email sending issue?

Kind Regards

Jonathan
