error message on all attempts to use contact form

See reCAPTCHA (v3) to set it up correctly.

That worked on one site but not the other. still a problem on https://www.whealassociates.com/contact/ despite being set up identically.

See FAQ > After submitting the form, I get an error message stating “There was an error trying to send your message.” What is wrong?

The border is red. None of the rest of the pages I followed helped with that. The from address is a real address and with <> round it.

Trying to replicate the other site, I installed WP Mail SMTP but I cannot set it up the same way as this account’s email uses Microsoft Exchange. Presumably your plug in requires me to get WP Mail SMTP to work first?

Do you know nay other plug ins that work standalone?

FAQ > I get an error message with a red border. So, how can I solve this?

That was about as unhelpful an answer as you could give. I specifically asked how to enable it using Microsoft Exchange email. If your system will not work with Exchange, just tell me that.
