Mulberry is a versatile, open-source email client originally developed for macOS, but it is also compatible with Windows and Linux systems. The application follows strict internet standards, supporting protocols such as LDAP, IMAP, IMSP, ACAP, and iCalendar. It also offers several security options, including message encryption and digital signature handling, ensuring safe communication.

Despite its features, many users choose to migrate from Mulberry to Outlook PST for several reasons:

  • Enhanced Productivity Features: While Mulberry focuses primarily on email, Outlook integrates email management with calendars, tasks, and contacts, tools widely used by professionals.
  • Stronger Security and Privacy: Compared to Mulberry, Outlook provides more robust encryption, access controls, and privacy measures.
  • Better Email Management: PST files offer greater flexibility for organizing, archiving, and searching emails efficiently.
  • Multi-Device Accessibility: Outlook PST data can be accessed across multiple devices, enabling users to work seamlessly from anywhere.

How to Export Mulberry Emails to Outlook – Step-by-Step Guide

Converting Mulberry emails to Outlook involves a two-step process to ensure all messages are transferred safely and accurately.

Step 1: Locate MBX (MBOX Variant) Files from Mulberry

The first step is to access the Mulberry mailbox files, which are stored in the MBX format, a variant of MBOX. These files contain all your emails and need to be extracted before importing into Outlook.

Depending on your Windows version, the default locations for Mulberry mailboxes are:

  • Windows XP: C:\Documents and Settings\Administrator\Application Data\Cyrusoft\Mulberry\Mailboxes\
  • Windows 7, 8, 10, 11: C:\Users\(Your Username)\AppData\Roaming\Cyrusoft\Mulberry\Mailboxes\

Navigate to the appropriate folder and copy the MBX files to a secure location. These files will be used in the next step to migrate your emails into Outlook.

Step 2: Convert Mulberry Mailbox Files into PST Format

Once you have located and secured your MBX (MBOX variant) files from Mulberry, the next step is to convert them into Outlook PST format, which can be directly accessed in Microsoft Outlook. Since Outlook does not support MBX files natively, a professional conversion tool is required.

One reliable solution is MacArmy MBOX to PST Converter. This software is designed to efficiently convert mailbox data from MBOX or MBX files into PST format, ensuring no data loss.
