What is PST?

A PST file, or Personal Storage Table (.pst) file, is a Microsoft Outlook data file that stores users’ Outlook data for POP3, IMAP, and web-based mail accounts, including all mail folders and folders. Includes items within, such as Email, Email Attachments, Items and Appointments, Contacts and more.

What does PST mean?

Personal Storage Table files are used in all versions of Microsoft Outlook from Outlook 2000 to Outlook 2016. In early versions of Outlook (Outlook 2000 and Outlook 2002), PST files were stored in ANSI format and had a maximum size of only 2GB, while later versions save PST files in Unicode format with a maximum size of 20GB ( Outlook 2003 and Outlook 2007) and 50GB (for Outlook 2010).

PST files can be compacted using the “Compact Now” option in the Data File Management area of ​​Outlook, and corrupt PST files can be repaired using Microsoft’s ScanPST application or a third-party application .

A similar Outlook data file known as an OST file or Offline Storage Table (.ost) file serves as the cache for Microsoft Outlook’s Cached Exchange Mode feature.

As with OST files, Microsoft Exchange Server and Microsoft Hotmail (via the Outlook Hotmail connector) store versions of users’ Outlook or Hotmail data on the local computer instead of on the mail server to provide these contents .

Unlike PST files, OST files are associated with mail account configuration and cannot be opened or backed up individually.
