Send RFQ to vendor through email functionality in AX 2012

Dear All,

We would need to send RFQ to vendor. it should send automatically to vendor email id based on vendor master setup.

Steps:

1. In email parameters setup is done.

2. Defined the email id in user profile which is available in system parameters.

3. Send RFQ to vendor through email is working. able to receive email as well along with RFQ document.

4. In other user id, as per employee relations, email id is updated based on employee master. here, when we try to send RFQ to vendor. its not working. we are getting error message.

is it not possible to send RFQ other than email which is defined in email parameters ?

is there any setup for that ?

Please provide input.

Thanks.
