Note:
In above <password> field i tried to give both gmail password and App Password, none of them are working.
Project is imported from Getting started page of WSO2 Integration Studio 8.0.0
I followed below prerequisites suggested by WSO2 Doc
Go to the security tab in your account settings and turn on less secure app access.--> this option not supported by google, so i tried App Password
Go to the gmail settings -> Forwarding and POP/IMAP and enable IMAP under IMAP access.

How can we resolve this?

Answer 1

can you try with outlook smtp? Please check with outlook and see if
you are able to receive emails via email connector. Server Address: smtp-mail.outlook.com Username: Your Outlook Email Address (e.g. example#outlook.com) Password: Your Outlook Password Port Number: 587 (With TLS = true) You can try Gmail connector as
well

I also noticed that you are sending attachments in postman while its not handled in your API
