I was flailing around trying to find the subject menu option, and wound up finding the answer here, the essential info of which is:
Tools/Import Export Settings, Reset Settings (Don't backup if you dont want to), select general profile. You should then see the exception item on the debug menu.
Customize
If you don't want to erase all your existing options, you can also just add the command to the menu:
Right click empty space in a toolbar and select Customize.
On the Commands tab, select Debug in the left list and locate Exceptions... in the right list. Click Exceptions... and drag it to the Debug menu on the menu bar, then drop it where you would like it to appear in the menu.
This works for any other command in the list as well.
