Step 1: Export and Save Zimbra Emails in EML Format

• Launch Zimbra desktop client and click on the Preferences tab.
• Now, from the left pane, choose Import/Export.
• From the export panel choose All Folders.
• At this point, you can either select any individual mailbox item or the whole mailbox. Click OK to proceed.
• Click on Export to begin the process.
• Next, provide the destination to save the mailbox items.
• The exported items are compressed in a ZIP file and are required to be unzipped. Use proper tools like WinZip/ WinRAR to unzip the file.
• Next, check the extension of the unzipped mailbox items. At present, Zimbra only allows EML format for exporting the mailbox files.

Step 2: Migrate EML Files to Outlook

• Open your Outlook desktop client and select the Folder tab from the ribbon. Next, click on the New Folder tab.
• Provide a new name for the folder.
• One can now directly drag and drop all the EML mails into this folder.

• Click on the Import & Export tab. This will open up Import and Export Wizard. From the list, select Export to a file.
• Next, select Outlook Data File (.pst) option.
• Select the folder containing the Zimbra backup files.
• Click on the Browse button to save the file to the desired location.
• Check the prior assigned location for the saved PST file.

You are done!
