Workflow to Email on Discussion Board Reply

Thanks for testing Simon! I haven't tried using a SP Designer workflow. Nor have I tried on a new discussion board. I'll try both those and report back tomorrow. :) 

Ok so I ran some tests this morning. There are two things that are custom on the discussion board that I am experiencing the problem with. I added two columns. A people picker column titled "Stakeholders" and a text field titled "Subject". I also created a new View with grouping on the column "Subject".

So for my testing, I created a brand new discussion board and did not add any columns or views. I created a workflow to notify me on any new or edits. Both the new notificaiton and the notification on Reply worked successfully. I then added the "Stakeholders" column and changed the workflow to email the "Stakeholders" on any new or edits. I created a new discussion and also a reply to it and both notifications came through successfully. I then created a View with grouping and I created a new discussion and also a reply to it. The notification on the new discussion came through but the Reply notification did NOT come through. I removed the grouping from the custom view and created a new disuccsion and reply. The reply still did NOT come through. So, I deleted the custom view completely and created a new disuccsion and reply. The reply still did NOT come through.

I created a new discussion board again. This time I created "Stakeholders" people picker. I created a workflow to notify Stakeholders. This time the initial notification came through but Reply notification did NOT come through. So I changed the notificaiton to notify me directly and not use the Stakeholders field. The initial and reply notificaiton came through with success. I changed it back to use Stakeholders and the reply notificaiton did NOT come through. I created yet another test discussion board and tried this again to make sure it wasn't a fluke. It is repeatedly recreatable.

So long story short. It is the people picker column that I used for email notifications that is not receiving the notifications on replies to the discussion board thread. I am going to do some more testing to see if this also happens on regular lists or if it's just discussion boards.
