Can I use my external email client for sending emails while clicking on Email invoice button in Manager?
I wish I could make this possible but it’s not that easy. There are too many email clients and no generally supported standard.
The closest you can get right now is to use custom SMTP server when sending emails out of Manager. Depends who is your email provider, they can automatically copy all emails sent through your custom SMTP server to your “Sent emails” folder which means it would look like sending your external email client itself.
Then can i export my invoice or any other document to pdf format in one click . i am not convinced by this route (print / print as pdf option).
