I can't email invoices to customer. This issue it has been going on during the last couple months. Every time I am calling the representative resolving the issue for one day only and day after the issue start all over again. I don't have time to spend hours on the line for the same issue.
Solution 2: Ensure QuickBooks isn't running as administrator.
Right-click the QuickBooks Desktopicon, then select Properties.
Go to the Compatibility tab.
Deselect Run this program as Administrator.
If this option is grayed out, select Show Settings for All Users, then click Okay.
Solution 3: Ensure your email preference is entered correctly. Also, changing the sending port usually works. Check this out: Set up Email Service, then go to the ISP and Port Information link to see the list of ports in the table.
Solution 4: Ensure your email preference is set up correctly in the Internet Explorer browser.
Open the Internet Explorer (IE) browser.
Click the Tools menu or the Gear icon.
Select Internet Options.
Click the Programs tab.
Make sure the email is selected as the default email program.
Select the correct option, then click Apply and OK.
Close the browser.
Open QuickBooks and email the transaction.
