Im currently working on some code in a SharePoint application page to write to the workflow history list programatically – from outside the workflow itself! I will post the details up when I get it working, for all of you who are trying to view your workflow history list as a SharePoint list, it does exist! it’s just hidden from view by SharePoint, simply use the following url with your own site:
http://servername/sharepointsite/lists/Workflow History
!
I tried but not able to view any list
Sorry my url was wrong, you need to add ‘lists’, see below:
http://servername/sharepointsite/lists/Workflow History
