I recently moved to a new company. I have 5+ years worth of email from my previous employer that I backed up off my Zimbra user account and would still like to have access to the email content when I need to reference old information and/or contacts.

Since I am no longer at the previous company, I obviously no longer have a mailbox account on their Zimbra server. However, I would like to use the Zimbra Desktop client to just access my backed up email without the need for a Zimbra Server account. I'm not finding a way to do this since the Zimbra Desktop client requires an account to be created immediately upon installation. There appears to be no way to just launch the client and import a backup to access the emails without first setting up some type of account. Is there any method for this?
