This seems to be caused by a number of things, most popular being uninstall of Google Chrome that doesn’t cleanup properly.

Close Outlook and any open Internet Explorer windows and re-open Outlook and try to click on the hyperlinks in the email. They should now work.

   REG ADD HKEY_CURRENT_USERSoftwareClasses.htm /ve /d htmlfile /f
   REG ADD HKEY_CURRENT_USERSoftwareClasses.html /ve /d htmlfile /f
   REG ADD HKEY_CURRENT_USERSoftwareClasses.shtml /ve /d htmlfile /f
