Ever wonder how Office stores your calendar, notes, tasks, and emails? When you receive an email or create an event, Outlook stores that information in either an .ost (Off-line Storage Table) or a .pst (Personal Storage Table) file. This allows you to migrate or transfer your Outlook data from one computer or another fairly easily.
Love it or hate it, Outlook is one of the most widely used desktop email and calendar software solutions. Microsoft Outlook was first released for MS-DOS as a component of the software company’s Exchange Server platform.

In short, it is kind of a mystical part of the Windows Operating System. Luckily, there are ways to modify the registry directly using the built-in Windows tool regedit. Please note, registry edits can be and should be considered dangerous! It is always smart to back up a registry “key” before modifying it. If you’re unfamiliar with editing the registry, it is best to leave this to a professional.
