Automatic Login
Outlook Password Retention
and Related Troubleshooting
Outlook may continue to prompt for your password each time you start it, even though you've checked the box that you want Outlook to retain the password. The following steps will normally enable Outlook to retain the password correctly.
It is actually your Internet Options settings that allow automatic login. Adjust them as follows.
Open Internet Options through Control Panel or from within Internt Explorer. Use the search box in Control Panel or in IE, Tools menu, Internet Options.
Once you're in the Internet Options go to the Security tab, Local Intranet, Sites, Advanced. The dialog shown below will appear.
Add the Outlook Anywhere URL to the Local Intranet zone. See screen shot below. The URL to add here is https://mail.webville.net While you're here, if you have SharePoint and you'd like to make that login easier, add your SharePoint URL here as well.
Click the Close button and Ok button to return to the security tab. While on the Security tab, select Local Intranet zone and click Custom level. The dialog shown below will appear. Scroll to the bottom and verify that your computer is set to allow Automatic logon in the Intranet zone. That's the default setting, you probably won't need to change it. See screen shot below.
Click Ok to close the Local Intranet Zone security settings dialog. Choose the Advanced tab of the main Internet Options dialog. Look near the bottom of the settings list under Security for Integrated Windows Authentication, it should be enabled. See screen shot below.
The above is normally all that's required. If you still have problems after doing all that, continue to these additional steps.
In Outlook 2007, find Account Settings on the Tools menu. In Outlook 2010, find Account Settings on the File tab. Select the Exchange account and click the Change button, then More Settings. Look on the Security tab for the Always Prompt for logon credentials checkbox. This checkbox must be cleared.
Verify the credentials are saved in the Windows user account. Scroll to the bottom of this page for Windows XP steps. In Vista or Windows 7, type Credential in the Start search field. Find the server address and click it to expand it. Edit or add mail.webville.net if necessary.

The Add button may not be available in Windows XP Professional or Home editions depending on a registry setting. You can change this registry setting if necessary.
