Hello Readers! This technical guide is for users who want to import PST to Zimbra Mail account. If you are switching from Microsoft Outlook to Zimbra and want to move your existing emails, this article will help you understand the process clearly.

Microsoft Outlook stores mailbox data in PST (Personal Storage Table) files. These files include emails, attachments, contacts, calendars, and other mailbox items.

Zimbra, on the other hand, is a web-based email platform widely used by businesses and organizations for secure communication and collaboration.

Because both platforms use different mailbox formats, transferring Outlook data to Zimbra can be confusing for many users.

Outlook uses PST format
Zimbra uses TGZ backup format

Since Zimbra cannot directly open PST files and Outlook cannot export emails to TGZ format, users need a proper migration method.

In this guide, you will learn the easiest way to import PST emails to Zimbra Mail without losing data.

Can Zimbra Import PST Files Directly?

No. Zimbra does not support PST files directly.

Zimbra imports data using TGZ backup files or IMAP-based migration, while Outlook stores data locally in PST format.

To move PST data to Zimbra, users typically need to:

Convert PST emails into a compatible format
Upload emails using IMAP migration

Without a conversion or a migration tool, PST files cannot be imported into Zimbra Mail.
