I hope someone in the community can help because this issue is really
annoying. There doesn't seem to be any help for it online.
When I try to send an email the below message comes up (please do not
suggest checking the authentication setting as I have tried almost anything
to get it to work).
Thank you to anyone that can help!
The message could not be sent. The authentication setting might not be
correct for your outgoing e-mail [SMTP] server. For help solving this
problem, go to Help, search for "Troubleshoot Windows Mail", and read the
"I'm having problems sending e-mail" section. If you need help determining
the proper server settings, please contact your e-mail service provider.
