Extracting email from Zimbra is not all that challenging. These simple steps show you how.

With Zimbra being cloud-based, you do not tackle it for forensics at the server itself. Instead, you can deal with each mail archive separately. This is a great option when the discovery of email processing might be limited to a single custodian.
If you go into Zimbra and select the following options you will be provided with an offline backup of the mail archive associated with that account:
Exporting all account data:
– Go to Preferences>Import/Export
– In Export, select the Type as Account
– Make sure Source displays All folders.
– Click Export.
– In the dialog that opens, select Save File and select where to save the file.
The account data is saved as a tgz file.
The .tgz file is an archive which you can extract and add folders with emails as Email file evidence (E3/Add Evidence/E-mail database/Email file).
There is also an option to convert Zimbra mail files into PST files using 3rd party tools. You can see more details on this option here:
We made the support of Zimbra mail even easier in the 1.7 version of the E3 Platform with a quick parsing of the mail archives.
