I've chatted with a few agents online and they have been unable to resolve my problem.
When you bring up the customer list in QBO, if there is an email associated to that customer there is a small email icon next to the customer name. When I click that email icon, it opens up my personal Comcast / Xfinity email account to generate the outgoing email. However, I want to change this so that it opens up my Gmail account but cannot figure out how to make this change.
Ryan, thank you so much, you set me on the right track and I have finally solved the problem. I thought it was a QBO issue but you were correct, it was more due to my setting stored on my browser.
In case anyone else has this problem, to correct it I opened up Chrome, clicked on the three dots in the upper right hand corner. Then selected settings, advanced, site settings, handlers. Clear those out, then open up Gmail. select the gray diamond in the URL box and allow Gmail to be the default.
