No, WEBii does not back up your email messages on the backup server. If you have already downloaded your email messages to your computer, there will no longer be any copies of those messages on the server. If you have only used the Webmail program to check your email, there may still be copies available on the server which you can download using another program (such as Outlook, Mail, or Thunderbird).
We strongly recommend saving copies of your important email messages to your local computer or third-party program.
