It's very likely that your password is stored in your Email program and you need to change it to the new one there as well. You can confirm this by logging in to CubMail to ensure your password was changed to what you thought you changed it to. If you can login into CubMail, you know your password. Failing to login to your email using a software program such as Thunderbird means you have stored your old password in your Email program.

Below are instructions for removing saved passwords from various email programs:

• Netscape 7+
• Outlook Express
• Mac Mail
• Outlook Professional
