How can I create different alias for my accounts?

[hamish]

Hello

I have some email acccounts on my PC. THe emails all come onto my Exchange server and I access that server through Outlook.

I have three accounts which all go into my Exchange mailbox. When I send an email, it always goes out with my default email address and signature.

What I would like is to create an alias that I can select so that I can choose what the displayed sender's name and signature should be. I could type in the from address in the From field each time, but that is aweful.

THere must be a way to create different accounts and then selec that account when sending. Is this possible? If you have three POP accounts, then you can choose the account when sending and it performs the same task. Can I do this without POP accounts?

THanks you loads in advance
