A current Zimbra Web Client user has used her email for years, and now is preparing to leave the organization that provides the service. She would like to download and save all emails, attachments, briefcase items, etc before all access is lost upon her separation. The files need to be "real" looking, not messy txt files, if that's possible.

Any suggestions? I am not super tech savvy, so please be kind and give detailed directions.

Thanks in advance for any help you can provide.
