No Hyperlinks in Plain Text anymore

Outlook 2007, Outlook 2010 and Outlook 2013 have an option to recognize Internet links in a message and turn that into a clickable link. By default this option is turned on.

If this option inadvertently got turned off (or if you actually prefer to have it turned off), you can change it in the following location;

• Outlook 2007
  Tools-> Options-> Mail Format-> Editor Options…-> tab AutoFormat
• Outlook 2010 and Outlook 2013
  File-> Options-> section Mail-> Editor Options…-> AutoCorrect Options…-> tab AutoFormat

Here make sure the following options are selected;

• In section Replace;
  Internet and network paths with hyperlinks
• In section Always AutoFormat
  Plain text e-mail documents

The above settings are responsible for recognizing hyperlinks in your emails.
