Error Message in Internet Explorer: "Conditional Compilation is turned off"

When you browse to a page using Internet Explorer, you may receive an error message similar to the following: 

The problem occurs because the page being browsed to contains an anchor tag (<a>) and the tag's onclick property value contains an "@" character. For example, the onclick property value of the anchor tag contains a mailto: link, such as example@microsoft.com

The onclick property value for the anchor tag (<a>) should be set to a script function. If the purpose of setting the onclick property value to a mailto: link is to invoke email, use the href property value of the anchor tag instead of onclick. Otherwise, ensure the onclick property value of the anchor tag calls a script function.
