An OST file, also known as an Outlook Offline Data File, is a local copy of your mailbox data in Microsoft Outlook. It is created when you configure Outlook to work with a Microsoft Exchange Server or Office 365 account in Cached Exchange Mode.

The purpose of an OST file is to allow you to access your mailbox data, including emails, contacts, calendar events, and other items, even when you are not connected to the server. It enables you to work with your Outlook data offline and synchronizes any changes you make when you reconnect to the server.

When you are connected to the server, Outlook automatically synchronizes the changes made to the OST file with the Exchange Server or Office 365 account. This synchronization process ensures that your mailbox data is up-to-date and consistent across different devices.

Reasons to View, Open and Read OST file with attachment

There are several reasons why you may want to view, open, and read an OST file with attachments:

1. Offline Access: OST files allow you to access your mailbox data even when you are not connected to the server. By opening and reading the OST file, you can view your emails, contacts, calendar events, and attachments without an active Internet connection.

2. Data Recovery: In case of an issue with the Exchange Server or Office 365 account, you may need to recover data from your OST file. By opening and reading the OST file, you can extract important emails and attachments that may not be accessible through other means.

3. Historical Reference: Sometimes, you may need to refer back to old emails and attachments stored in the OST file for historical or reference purposes. Opening and reading the OST file allows you to retrieve and review this information without relying on the server connection.

4. Exporting Specific Items: If you only need to export or save specific emails or attachments from your mailbox, opening the OST file gives you direct access to the content. You can select and extract the required items without having to synchronize the entire mailbox.

5. Attachment Retrieval: If you are specifically interested in accessing or saving the attachments within your emails, opening and reading the OST file allows you to locate and extract the attachments directly. This can be useful when you need to access files or documents sent to you via email.
