How to Bulk Convert Multiple PST Files on macOS?

Transfer of data between different operating systems or archiving of old email databases results in various compatibility issues. In case you need to deal with a macOS environment that contains a set of old .pst files created on Windows, you will be facing another unique challenge.

Microsoft Outlook for Windows combines emails, contacts, calendars, and tasks in the PST format. On the contrary, macOS uses another set of file formats (e.g., MBOX, EML, OLM, or native database of Apple Mail). Although processing one .pst file might seem cumbersome, managing and converting multiple .pst files manually in macOS would become a tough task indeed.

This complete guide will help you understand the challenges of .pst management on cross-platform basis, look into the disadvantages of doing things manually, and introduce the best professional solution—MacMister PST Converter Tool.


The Challenge of Handling Multiple PST Files on a Mac

In the process of switching from Windows to Mac or consolidating information from various ex-employees or personal accounts, you are most likely not dealing with one file. Rather, you have a folder with numerous PST files of various sizes.

Trying to work with these files in a Mac system will show several limitations of the files:

  • No Native Support: Applications native to a Mac OS (such as Apple Mail and Mac Outlook) do not provide native support for Windows PST files.
  • Sizes and Volume: PST files are quite large since they store years’ worth of e-mail messages and attachment in one file format. Several PST files can overwhelm regular system applications.
  • Folder Structure: Manual import/export of the files does not preserve the folder structure.

Considering that manual methods of dealing with the files imply either launching Windows system for each individual file or slow cloud-based synchronization process, bulk processing software is a must-have solution.


Why Manual Procedures Fail for Bulk Conversions?

Other users attempt to employ free online conversion tools or create IMAP cloud sync for email migration manually:

  • To make an IMAP account as a channel for migration, you need to configure your Windows PC properly, import PSTs one-by-one into your Outlook and transfer them using cloud service and then get emails back on your Mac computer. Such process may take several days when there are many PST files and will face severe network issues and data loss problem.
  • Forwarding any private or corporate email database to an online conversion service, where there is already a history of years of financial and legal correspondences saved, will become a great security threat.
  • As for most cases, email conversion made by means of free or basic scripts will not give you read/unread flags, precise time stamps, or inline attachments.
  • The only way out – desktop application for batch processing.
