This message : No authentication mechansims supported by both server and client thrown due to exception javax.mail.AuthenticationFailedException from the SMTP server.
This typo error is not a WFA bug.
The possible reason as I see it is Authentication failure. It could be due to incorrect way of providing username/password. Can you provide the screenshot of the way you have given your username and the error it throws?
The mail server (Exchange) is perfectly happy to take "manual" input if I open a telnet session onto port 25 so there is no authorisation being requested. I get the same message whether or not I enter a username and password (and if I do, whichever of the formats you suggested I use).
Sender Email ID will be set during installation of WFA. You can change it if you have to. Some SMTP are configurd for Authentication access, you have to provide credentials of the Sender email in the Username/passwd
2. WFA has self-sending email notifications for workflow executions states. It means that notifications by email are only sent to the user who executed the workflow.
3. So now every user who wants to receive email notifications needs to login and go to Administration -> Accout Settings and enable the notifications
4, Or alternately the Admin can do it for all users.
