This does not appear to be a Tableau Problem. It appears that your PC does not have a default app configured for sending email. Take a look at this for how to do that: https://pchelp.ricmedia.com/change-default-email-client-windows-10/
Hi Ken Flerlage,
Thanks for your reply. You are right. It is not a Tableau problem. IT helped me to fix it. Now I can open email in Gmail now.
Ah, that's good. Would you please mark one of the answers here correct, even if it's your own, so we can close out this thread?
We installed Affixa to open Gmail.
