It helps users access mailbox data stored in PST files, even when Outlook is unavailable or the original email account is no longer active. The software is useful for individuals, businesses, IT administrators, and professionals who need to inspect, read, and manage archived Outlook mailbox data. The software allows users to open and view PST files created by different supported versions of Microsoft Outlook. It supports both ANSI and Unicode PST files, enabling users to access mailbox data stored in older and newer Outlook data file formats. Users can load a PST file directly into the application and explore its contents without configuring an Outlook profile or connecting to an email server. SysTools PST Viewer provides access to different types of Outlook mailbox items, including emails, contacts, calendars, tasks, notes, journals, and other supported data. Users can browse mailbox folders and view individual email messages with important properties such as From, To, CC, BCC, Subject, Date, Message Body, and Attachments. This makes it easier to inspect archived correspondence and locate specific mailbox information. The application maintains the original folder hierarchy of the PST file, allowing users to navigate through Inbox, Sent Items, Drafts, Deleted Items, and custom folders. Preserving the folder structure helps users understand how their mailbox data was originally organized and locate the required information without manually sorting individual messages. SysTools PST Viewer also supports viewing email attachments and other associated message content, depending on the file and attachment type. Users can inspect important documents and files stored within Outlook emails without having to import the complete PST into Microsoft Outlook. This is particularly useful when reviewing archived business communication or accessing attachments from older mailboxes. ![SysTools PST Viewer](https://images.g2crowd.com/uploads/product/image/large_detail/large_detail_939c6b69f2f1e0943654558f1e74bc83/systools-pst-viewer.png "SysTools PST Viewer") SysTools PST Viewer Discussions Most CommentedMost HelpfulCommon QuestionsNewest Showing **1** discussion ![Pinned by G2 as a common question](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Pinned by G2 as a common question") G2 Pinned by G2 as a common question • about 3 years ago More Options - Share [![linkedin](/assets/social-logos/linkedin-afe65e46604a5bd5105ab9c856116204040b6b3f2b2d42562fc8071ca0c48ca0.svg "linkedin")](https://www.linkedin.com/shareArticle?mini=true&summary=What+is+SysTools+PST+Viewer+used+for%3F&title=What+is+SysTools+PST+Viewer+used+for%3F&url=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-systools-pst-viewer-used-for) [![twitter](/assets/social-logos/twitter-61aaec80434c71387b8f7326e480592eae71c0a65afd051d66fce9b75a9bf417.svg "twitter")](https://twitter.com/intent/tweet?text=What+is+SysTools+PST+Viewer+used+for%3F&url=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-systools-pst-viewer-used-for&via=G2dotcom) [![facebook](/assets/social-logos/facebook-350d0b410d6b10debcf893050e803a8633d53561aa42807b087b8daf9be3668f.svg "facebook")](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-systools-pst-viewer-used-for) [![gmail](/assets/social-logos/gmail-6db42f21e7c254fae201b112bef0dd15d25223a5cbb32691ce80eab43761eadf.svg "gmail")](https://mail.google.com/mail/?view=cm&fs=1&tf=1&to=&su=What+is+SysTools+PST+Viewer+used+for%3F&body=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-systools-pst-viewer-used-for%0aWhat+is+SysTools+PST+Viewer+used+for%3F) [![mail](/assets/social-logos/mail-d55c53b04bf49872e40cd2443b85a99caa23394e6cf154ae32a9d08377c15d86.svg "mail")](mailto:?subject=What+is+SysTools+PST+Viewer+used+for%3F&body=https%3A%2F%2Fwww.g2.com%2Fdiscussions%2Fwhat-is-systools-pst-viewer-used-for%0aWhat+is+SysTools+PST+Viewer+used+for%3F) - Copy link - [ ## What is SysTools PST Viewer used for? ](/discussions/what-is-systools-pst-viewer-used-for) What is SysTools PST Viewer used for?
