A GUI PST viewer for Linux: rare, but here
If you have looked for a PST viewer that runs on Linux, you already know the options are thin. The tools that exist — readpst, libpst — work, but they are command-line converters, not viewers. They output mbox files rather than letting you browse a PST archive interactively. Most graphical PST viewers are Windows-only applications.
The PST Viewer is a native Linux graphical application. It opens PST files directly, lets you navigate the folder tree, read emails, and save attachments — without Wine, without a virtual machine, and without running a single command in a terminal.
What you can do with the PST Viewer on Linux

Open and read individual emails, including HTML-formatted messages and inline images.

Native Linux — no Wine required
The PST Viewer is built to run natively on Linux. There is no Wine dependency, no compatibility layer, and no emulation overhead. It installs like any other Linux application and reads PST files using its own built-in PST parser.
Supported Linux distributions
The PST Viewer supports:
- Ubuntu (LTS releases)
- Debian
- Fedora
If you are using another distribution, contact us — support is growing as the tool develops.
PST Viewer vs readpst / libpst on Linux
readpst / libpst — command-line tools that convert PST files to mbox or other formats. Useful for scripting and batch processing, but they require terminal use, produce output files rather than letting you browse interactively, and can have edge cases with encoding or attachments that require additional handling.
PST Viewer — a graphical application. Open the PST file, click through folders, read emails, save what you need. No conversion output to manage, no command-line flags to learn. Better suited when you need to browse or retrieve specific content rather than batch-process an entire archive.
Common use cases on Linux
Migrated from Windows. You moved to Linux and brought a PST archive with you. You still need occasional access to old email without setting up a Windows environment.
IT or sysadmin work. You manage PST backups or eDiscovery exports and need to inspect their contents on a Linux machine.
Received a PST file. A contact sent you a PST archive and you need to find a specific email or document inside it.
Just want to check. You have a PST in a backup and want to verify it is intact and readable before deciding whether to migrate its contents.
Completely free
The PST Viewer is free on all platforms, including Linux. No licence key, no trial mode, no feature limitations. It does not require an account, does not send data anywhere, and works fully offline after the initial download.
