Questions Default email for specific users.

Hi,

 I am in the process of implementing email in Acumatica and have been having difficulty in figuring out how to have the users email address populate automatically  in the email that is being sent. 

 My setup is that each user has there own email setup as a system email. When sending an email from any screen the email field remains blank and the user needs to select the email that they wish to send from.

 I do not wish to have system emails that are department based...I would like each user to send and receive from their own email address.

 Any advice would be appreciated.

Thanks.
