As long as your Exchange server is configured to allow SMTP sending, you should be able to supply the proper credentials and get it to work.
This would also include external providers such as gmail, etc. Just be careful that you're not transmitting unencrypted company private data out to a public network.
I've been successful using several providers including Exchange, gmail and my own private POP3 account.
