Nintex workflow 2010 - Flexi task not sending emails
I have a workflow that worked for a long time with no problem and is now seemingly randomly not sending the task email. I've tried changing many things in the workflow that might be causing the problem. I've looked at the html in the email, the variables, the text in the form. I've tried recreating the form and rerunning it. It doesnt seem to matter what I do, the email never sends. I've changed who I'm sending it to. I've tried adding a new flexi task and only adding an email address, not changing the default values in the task. I don't want to rewrite the workflow as it is a large one.
Has anyone come across tasks that suddenly stop sending emails?
