Hi Ailene, 

Thank you for your detailed response. The message settings location is where I have to go to change the email subject line back to what I want each time QBO changes it. I will try using an incognito windows for QBO alone to see if that helps. My account automatically logs me out after a period of inactivity. My systems exceed the minimum specs required to use QBO. It will be within the next week and a half that I expect QB to make the change again based on past history. I will send you an update in two weeks. I've marked it on my calendar. 

Thanks again,

Andrea
