Hi, Im changing jobs after a very long time and need to keep my emails / contacts with me after i have gone. The new company does not use zimbra.

I have been using zimbra at work and the desktop version while at home which currently syncs while I'm an employee. My email account will be switched off when i leave. will zimbra desktop retain all my emails/contacts? how do i make sure my mails and contact are safe so i can refer to them in future?
