Send mail from outlook by selecting particular account

Hi friends,
The programme is working fine and sending the mails correctly. I have two accounts configured in outlook. One is default.

The problem is that each time the mail delivers from default account which I don't want. I have added a code to send the mails from that particular selected account but the mail delivers from the default account. Please suggest me solution for it.

For example:

my default account is: abc@gmail.com
Second account is: mukeshbaviskar.nsk@gmail.com


The mail delivers from abc@gmail.com each time but I want to send some mails from my second account mukeshbaviskar.nsk@gmail.com.

Solution please!

Sincerely,

Mukesh
