Sending from one email address

I am a little confused.

If you are retrieving your home email at work in outlook you should already be logged on to their mail server and able to send.

The other option would be to use whichever accout you are useing from the office to connectto the Internet, it should include use of their mail server

In Tools|Services you can add a new account, and use your home credentials. When you launch Outlook you can select which profile to use, and you'll be able to send/receive the mails for that account. Provided that your firewall at work will allow you to do so, they may have a port blocked (like we have, grumble).
Careful though, you may have a half mailbox at home, and a half mailbox at work. Might get a little confusing...

Yes. Just dig around inside Outlook. I assume you have 2 profiles, one for "Real Work EMail" and one for "Home EMail while @ Work". Go into this 2nd profile and you will find a tab to configure the servers that you use. Leave the server for retrieving email (POP3) so it still points to your "@ Home" ISP. But change your outgoing (typ. SMTP) server to point to your SMTP server at work. You may have to fiddle with authorisation settings, etc. Often, you will just get prompted to log into the SMTPserver, using your NT (I assume) domain user name and password.

Some explanation: Your ISP, like most ISPs will let you pick up email from anywhere/any network, but will only accept outgoing messages from a systemn directly connected to their network. It is believed that this will help slow down a lot of SPAM. It's important for ISPs so their resources aren't being used/wasted by somebidy "outside", and also to limit their legal liability.

It sounds as though you're looking for a workaround but you may not need one. You actually can send from your home address (even at work) if you like. There's a box under the account properties labelled "my outgoing server requires authentication". Put your login id and password there, and it will sign in and send things for you. This might be the better way to go, since then your personal outgoing email will be sitting on your home server instead of your work one, just in case anyone looks;-)

You go to tools/accounts, select the @home account set up to receive your email, and click on properties. The second tab is called Servers. Down the bottom is a section for "Outgoing mail servers" and that's where you find the option.

You will have to speak to your Exchange administrator to let you send email and how to set it up. Most administrators set it up so you can't send email using your Exchange server as the SMTP host only if the server recognizes who you are, this is done for security reasons.
To make sure that this is the problem at a command prompt type the follwoing (you will not see what you type so make sure you type it correctly):
telnet yourservernameoripaddress 25
mail from: youremailaddress
rcpt to: anyemailaddress
if you receive a 550 relaying is prohibited then the problem is because your admisitrator has blocked relaying. If you however receive a 250 reply that means that outlook is not set up corrctly.
