How to enable authentication for outgoing email.

From the main outlook express window, select the Tools menu, and pull it down to Accounts

Selecting the Accounts option opens a list of accounts. Sometimes you will have more than one account listed.

Be sure the Mail tab at the top of this window is selected, then click on your account. It will probably be named mail.california.com, but may be named something different.

Click the Servers tab near the top of the window, and make sure, near the bottom of the window, that the checkbox My Server Requires Authentication under Outgoing Mail Server is checked, then click OK

If you have more than one California.com mail account listed here, you'll need to repeat the previous steps for each of them as well. Once you're finished, click the Close button.
