Thanks for the reply. Webmail is working fine on my QB. When I'm sending forms, invoices, it is working.

When I go to Customers or Vendors and click on their email address it gives an error "Your email cannot be sent because Quickbooks does not support the email program you are using".

Now, if I change my QB default email preference from Webmail to Outlook, and I perform the same steps, it works. A new Outlook email compose window appears and prefilled with the Vendor as a recipient. I think this is a glitch when the default QB email preference is set to webmail. Please send this to your development team to test and fix. Thank you! I tried showing this to one of your reps via screenshare. They failed to comprehend for 80 minutes and tried all the wrong troubleshooting steps and looking at the wrong places. I can't do it again, it's excruciating.
