Yes, that's what I needed. Outlook is the client or 'application'. The fix is made within the browser, I am assuming IE8 or 9. Click on Tools from the toolbar in Internet Explorer 8 (or 9) and select Internet Options . Then select the Programs tab from the top of the window to access the default browser settings. Click on the 'Make default' button, you can even choose to be alerted if Internet Explorer is not your default browser. Click OK to save your changes. Close IE and try again to access your hyperlinks. There is also a Microsoft 'Fixit' for this if the first step is unsuccessful. Here is a link that might be useful: Hyperlinks are not working in Outlook

Something simple you might consider trying first... Put IE9 in compatibility mode by clicking the little icon beside the address bar(see below). That will make your IE9 appear to be and supposedly render pages as if it were IE7. It may or may not help but it's easy to try.

Try this procedure... Open a webpage. Stretch it out to fullsize. Don't use maximize. Choose any link on that webpage and right-click> open in a new window. Stretch that second window out to the desired size- don't use maximize. Close the first IE window. Then close that second resized window. this is another method you can try Open a new Internet Explorer window. Without using the maximize button, drag the corners of the window until it completely fills the screen or it's the size you prefer. While holding down the Ctrl key, click on the menu File : Close. (Note: Do not use the [X] in the upper right corner to close the window.) Open a new Internet Explorer window. This time, the window should be the same size as you last had closed it. for me the first method usually works
