Emails from QBO was working fine for our company until yesterday when it suddenly stopped working for no apparent reason.

It has worked fine for years now all of a sudden it doesnt. Customers are not receiving invoices and we dont get a copy to our own email address either.

This is a major problem for us as we have automatically recurring invoices and have no way of knowing if they have been sent.

We have spoken to customer service and they were not aware of any issue with it but have escalated to the engineering team. I dont know how we are going to be able to work without this functionality.
