Were having the same problem. Using QuickBooks Desktop, in setting and alerts, there is only select home landing page?   

There are two notifications, the fist when the customer makes a payment, and the second when the Monies are going to be deposited in our Bank.  The first notification is going to the wrong email address, the second is coming correctly to me.  

We did not make any changes?   How do I change the first notification address?
