Microsoft does not offer a standalone PST viewer software. PST files are associated with Microsoft Outlook, and Outlook itself can be used to view the contents of PST files. If you're unable to open the .pst file in Outlook or if you don't have Outlook, you can use OST PST Viewer to open both .pst and .ost files.
Outlook Data Files (.pst and .ost) contains your messages and other Outlook items and is saved on your computer. Certain types of accounts, such as POP accounts, store their information in Outlook Data Files (.pst files). Most other account types, such as IMAP accounts, Microsoft 365 accounts, Exchange accounts, and Outlook.com accounts use an Offline Outlook Data File (.ost) file to store a synchronized copy of your mailbox information on your local computer.
Note: In Outlook 2013 and earlier versions, IMAP accounts also used an Outlook Data File (.pst). In Outlook 2016 and Outlook for Microsoft 365, IMAP accounts use Offline Outlook Data Files (.ost).
You can also use an Outlook Data File (.pst) to backup or export items from any type of email account.
