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.
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:
