That's what I was afraid of. I have customers that need to track ALL emails sent, so it looks like I will have to update their process diagrams to call workflow after every email is sent via email activity and write the email data to a custom table. While this will work for the normal email activities, it wont work for the built-in reminder functionality. Thus I will also have to go old school for reminders and just have timers attached to the user task that sends the reminders and then calls Workflow to write the data into SQL.
Seems like such an obvious thing to track with the Action History, so I am not sure why this data is not being captured by Forms already. I hope this is something Laserfiche will add to Action History so that it is available to view in Forms, written to the Action History when saved to Laserfiche, and able to be queried directly via SQL.
