can you pls upload the error you are receiving as well as any other console/error logs that you are seeing. Also pls mention which Mx and Email connector version you are using.
are you using basic authentication while configuring or using OAuth configuration? Are you sure that the client id/secret are correct if using OAuth. Also if you are using basic creds then pls refer the document - as basic (username/password) are not supported anymore and you would need to generate app password if you are trying to configure gmail.
Hi harikrishna ,
You can use the Email connector also in a native mobile project. For this download the Email Connector from marketplace then you can Java action named as 'Send Email' when you will use send email it will require two parameters one as 'account' and other one as 'message'. in account it will require the data of account from which you need to send messange so you can retrieve the Email_Connector.EmailAccount then you will get the account information and for message create object of email message and fill the details such as - to , body,content.
