What is OST?
OST stands for Offline Storage Table. It is a file format used by Microsoft Outlook to store a copy of mailbox data for Exchange accounts locally on the user’s computer.
OST files allow users to access their emails, calendar events, contacts, and other mailbox items even when they are offline or not connected to the Exchange server. Changes made offline in Outlook, such as composing emails or organizing folders, are synchronized with the server once an internet connection is established.

PST files can be imported or exported, making them useful for backup, archiving, or transferring email data between different systems or accounts. Unlike OST files, PST files do not require synchronization with a server and can be accessed directly without an internet connection.

Key differences between OST and PST
PST files are the most common format for storing email data. They are easy to create and manage, and they can be opened in a variety of email clients. However, PST files are not as efficient as OST files when it comes to syncing with email servers, so they can sometimes result in data loss.
OST files are less common than PST files, but they offer a number of advantages over their counterparts. OST files are more efficient at syncing with email servers, so you’re less likely to lose data. They’re also more compact than PST files, so they take up less space on your hard drive.
