At work, I can send and receive emails. Using the same email address, I would
also like to be able to send and receive emails at home.

At work, the company is with ISP xxx, xxx is also our SMTP service provider.
At home, I'm with ISP yyy. That is, the two ISPs are different.

Is it possible to setup Outlook to send emails to xxx's SMTP server using
ISP yyy?
