Send email from Excel via Gmail

In the prior solution, everything looks great but the code provided fails with the error "The transport failed to connect to the server".

I have all the smtp details specified, can someone assist with troubleshooting?

Many thanks!

Have you checked your firewall that its not blocking the port?


Yup, I can ping/trace to the gmail smtp with no issues.

Any other ideas?

Well, yes and no.

My intention was to have many other people with different configurations be able to submit this form with no additional configuration, is that not possible?

My assumption was that the code above would use the gmail smtp to send the email (unless blocked).

If not, is there another route?

It does not matter who uses the form but rather that that gmail account being used to send the email have POP enabled. Once this has been set up it the form should send email with no further configuration required (assuming no local issues eg firewalls)

Due to the fact that it is so easy to access VBA scripts, even when password protected, that I would set a gmail account specifically for the purposes of this script. That way if the login details are compromised it will minimise the possible harm.



Hit the mark. Many thanks!


Tested with all possible settings - ports, servers, different email accounts.

Still not working.  Can you recommend anything else I can try, please?

I'm desperate!

Many thanks,
