I assume that you mean a shortcut to the email client 'Outlook', rather than a shortcut to the web-based service 'Outlook.com'. (Only Microsoft could be stupid enough to give the same name to two entirely different things!).
Go to Start > Programs and look for Outlook there. (It might be under 'Microsoft Office'). If you can't see it, run a search for 'Outlook.exe'. Then right-click on it and select Send To > Desktop (Shortcut).

You might think it sensible but I've answered dozens of questions on here where people have written "I'm having problems with Outlook". It has sometimes then taken three or four posts to find out that they meant Outlook.com when I've been writing about the email client called Outlook (or vice versa)! How anyone can see them as 'the same' (and thus in need of a common name) when one is software that works with any POP3/IMAP email service and the other is a website offering a particular email service is beyond me!

Have you definitely checked everything listed under 'Programs' (or 'All Programs')? Outlook Express (which you now tell us it is, rather than Outlook) should be listed under 'Microsoft Office' or something similar. If it's not then the program file you're looking for is 'msimn.exe'. It's location will be something like 'C:\Program Files\Outlook Express\msimn.exe' (or simply search for it by its file name). Once you've located it, right-click and select Send To > Desktop (Shortcut)
i have checked there too - and nothing - its like it has been completley removed , and just to clarify what has dissapeared is "outlook 2013" which is what i use to send and recieve emails on
