    Hi Ram85SG,

    Can you capture the SMTP Mail Setup page?

    I got smtp mail setup guide in "S-002 Query and Excel Report.pdf" file (section 7) at my OneDrive. May be refer to my OneDrive and Yahoo_Mail_SMTP_Settings can help you!

     Hi Suresh,

    Hi Ram85SG,

    It is funny that almost google searching provide port 465.

    Your setup is nearly correct! Just change the port to 587 (as gmail), it (yahoo) works for me! I should update document to remember this :-)

    May be silly question.

    did you create yahoo account which you are using? a.approvals@yahoo.com

    Yes. Created that email for this specific purpose. Tested the email account on outlook and it worked fine.

    Thanks.

    I am not sure what do you mean by tested on Outlook.

    did you try to send mail from other emails to a.approvals? did you receive? and vice versa

    Tested on outlook:

    Used the smtp settings on Microsoft outlook to confirm mail account is working (sending and receiving)

    So Yes, I tried and it is working fine.

    Thanks.

    Rami
