5/5 - (1 vote)

Karry Jack’s Query: “I’m planning to shift from Kerio to Outlook, but I’m stuck on how to move my whole Kerio mailbox into a PST file. Is there any safe way to do this without getting into complicated steps?”

Export Kerio mailbox to PST file is required when users decide to switch to another email platform or want to have a reliable copy of their Kerio data stored in Outlook. Many users experience issues such as missing folders, disrupted structure, or large mailboxes that do not export cleanly. This guide outlines the available manual option for Kerio users and describes how to use an IMAP Backup Tool for the entire export.


Why You May Need to Convert Kerio to PST?

There are several everyday situations where exporting Kerio emails into a PST file becomes genuinely useful. Here’s a clear look at when this export makes sense:

  • Once you’ve exported, you’ll easily be able to open all of your Kerio emails in Outlook, without worrying about the setup issues you just experienced. 
  • Your attachments, contacts, and calendar information stay the same. 
  • The layout of your mailbox also remains the same, which makes it easy to find your folders. 
  • The PST file will work without issue in any version of Outlook.
  • It provides a safe backup to help avoid that unexpected loss of information.
  • Managing your emails will be much faster, as everything stays organized inside the one PST file.

Manual Methods to Export Kerio Mailbox to PST

If you prefer handling the export yourself, there are a couple of free approaches that can help move your Kerio mailbox into a PST file. Follow the methods below:

Method 1: Export Kerio Connect Email to PST Using IMAP 

  1. To begin with, open Microsoft Outlook and go to File -> Add Account.
  2. Type in your Kerio email address and move ahead to enter the IMAP details:
    • Incoming Server: imap.domain.com
    • Outgoing Server: smtp.domain.com
  3. Complete the login using your Kerio password and allow Outlook to verify the settings.
  4. Once everything is correct, Outlook will start syncing your Kerio mailbox. Wait until all folders and messages appear.
  5. Then, go back to File -> Open & Export -> Import/Export.
  6. Choose Export to a file -> Outlook Data File (.pst).
  7. Select the Kerio folders you want to export.
  8. At last, choose where you want to save the PST file, click Next, and then Finish, and migrate Kerio mailbox to PST.

Method 2: Export Using Kerio Outlook Connector

  1. Firstly, sign in to your Kerio mailbox using your regular login details.
  2. Then, install the Kerio Outlook Connector from the Add-ons section.
  3. Open Outlook and let the Connector sync your Kerio account with Outlook.
  4. Wait until all folders and messages are completely synchronized.
  5. Finally, use the same Export to PST feature inside Outlook (as in Method 1) to save your mailbox as a PST file.

Limitations:

  • Syncing a large Kerio mailbox takes a long time and may stop midway.
  • If the internet slows down, Outlook may not load all folders properly.
  • Large or heavy mailboxes may lag, freeze, or not load completely.
  • If the Connector stops responding, you have to repeat the whole process.
  • Both methods depend on Outlook, so any Outlook error can break the export.
