Macro to Change FROM Address in MS Outlook

Dear Experts,

I am using the following code to send bulk mails from my MS Outlook to multiple users. Few years ago, I found this code thru Google.

Now I have 02 Email IDs... this code helps me to send mail from Old ID (which is default in MS Outlook)... Now I need to send mails to multiple users with my New Email ID / 2nd Email ID (which is not a Default ID and it cannot be a Default ID for technical reasons).

Please help me in sending mails with my New Email ID. Attached file is for your reference.
or
Let me know, if there is any other way to send mail with my 2nd Email ID.
