When using SendMaiI, I set the option to store a password when the dialog box appeared, but it appears that credential is not being accepted by the SMTP server. I haven't been able to find any documentation on how to change it. Using
MailSettings -> <|"Password" -> Automatic|>
did not cause the dialog box to reappear but it did give
"MessageTemplate" :> MessageName[SendMail, "msgerr"],
"MessageParameters" -> Association]]
I went into my Wolfram Cloud account and I did see the Credentials file, but when I tried to delete it, it was immediately recreated.
How can I reset the password?
