Hello. We have a number of mailboxes that currently reside on a hosted Zimbra mail server.

The users use Outlook with the Zimbra connector to access their hosted mailboxes.

We now have our own Zimbra Appliance.

We would like to switch the hosted users to the in-house Zimbra Appliance.

If I understand correctly, their mailbox data is already stored on their local PCs.

How can we point their Outlook profiles to our own Zimbra appliance AND make sure that they retain their old mail data?


Sorry if this is something trivial.
