Email no longer creating when submitting form

One of the companies that my company works for has a pdf form that has fillable fields and at the end we hit a submit button, which then creates a draft email with all of the data in a .xml file.

Over the last few years many of our workers have noted that it stops working for them and it has finally happened for me. I have tried multiple email clients as a default client to send the emails, aswell as using older versions of the clients and older versions of adobe.

Nothing seems to work. Does anyone have any ideas about how to fix this issue?

Thanks in advance
