Zimbra to Outlook Email Migration

Zimbra Collaboration Suite (Zimbra Desktop and Server) supports the export of emails to mailbox format which can be converted to Microsoft Outlook or PST file. It requires some manual work to accomplish the data export however the rest of the data migration can be automated with help of our converter. The export process depends on the data source, so the methods are differ for the Zimbra Desktop and Server. We have described both of them below.

Do the the following to Export emails from Zimbra Desktop:

  1. Open Zimbra and log on using credentials of your account
  2. In the top navigation bar choose Preferences
  3. Click Import/Export in the list of preferences
  4. In the Export panel select the type Account as you want to export mailbox
  5. Online application will allow you to download the mailbox in .tgz format
  6. Extract .TGZ or .ZIP file you ghave downloaded to get the file of .mbox format
  7. Use the MBOX to Outlook Transfer utility to import Zimbra mailbox files into Outlook or convert them to PST format.

Zimbra to Outlook email migration.

Do the following to Export emails at Zimbra Server:

Run shell prompt and use the following command to save mailbox as ZIP file:

/opt/zimbra/bin/zmmailbox -z -m getRestURL \
‘//?fmt=zip&query=is:anywhere’ >

Do the following if you need to save mailbox file to .TGZ file:

/opt/zimbra/bin/zmmailbox -z -m getRestURL \
“//?fmt=tgz” > /tmp/archive_name.tgz

To keep the name for subfolders you may use the following command:

/opt/zimbra/backup/${mbox}_`date +'%Y%m%d_%H%M%S'`.zip

Where – is a user name of the account to export the mailbox and – is the name of archived mailbox file.

Now you have the user mailbox archived so first you have to extract the mailbox file(s) from the TAR or ZIP archive and save the mailbox file to the Windows based PC where Microsoft Outlook is installed,

Extract your mailboxes and use the MBOX to Outlook Transfer tool to import Zimbra mailbox files into Outlook or convert them to PST format.
