If your username is your domain name (ex: my-domain.ca), you will have to set it up manually
here. Otherwise (if it's just your email address), proceed as follows.
Start Outlook (you can find it under the Start menu)
Under the Tools menu, click Account Settings.
Click the New... button, make sure Microsoft Exchange, POP3, IMAP or HTTP is selected,
then click Next
Enter your name, your email address, and your password, then click Next
On the next screen, it should retrieve the server settings, and send a test email. If this doesn't work, you
may need to check that your email address and password is correct. (You can try manually setting it up
here). Click Finish.
