I have several Outlook PST files that contain years of email communication, attachments, contacts, calendars, and other mailbox items. I need to move some of this data into different formats for backup and archival purposes, but I am concerned about losing important information during the conversion.
For example, some of my emails need to remain accessible through another email client, while other mailbox data may need to be saved in formats such as EML, MBOX, MSG, PDF, or CSV. Managing each email individually is obviously not practical, especially when the PST files contain thousands of messages.
One thing I want to avoid is ending up with converted files where the original folders and subfolders are no longer organized properly. The PST files have a specific structure with Inbox, Sent Items, custom folders, and nested folders, so maintaining that hierarchy would make the converted data much easier to manage.
I have started comparing dedicated PST converter tools with manual Outlook export options. During my research, I came across the SysInfo PST Converter, which supports multiple output formats and appears to provide options for batch conversion, folder selection, email preview, date filtering, and attachment handling.
Before I decide which method to use, I would like to hear from people who have actually converted larger PST collections. Is a dedicated PST converter more practical when the same mailbox needs to be exported into different formats? How important are features such as previewing emails before conversion and preserving the original folder structure?
I am also interested in how attachments are handled. Some of the PST files contain documents and images that need to remain associated with the correct emails.
