FAQ: Outlook

What is a Microsoft Outlook pst file?

A Personal Folders file (.pst) is an Outlook data file that stores your messages and other items on your computer. This is the most common file in which information in Outlook is saved by home users or in most organizations.

Your items can also be moved or archived to an Outlook Data File (.pst). Because a .pst file is kept on your computer, it is not subject to mailbox size limits on the mail server. By moving items to a .pst file on your computer, you can free up storage space in the mailbox on your mail server.
