Microsoft Outlook is one of the most trusted email management applications used by professionals and organizations worldwide. It stores mailbox data such as emails, contacts, calendars, notes, and attachments in two primary file formats – OST and PST. While OST (Offline Storage Table) files allow users to work offline, PST (Personal Storage Table) files are more flexible and widely supported for backup, migration, and data recovery purposes. Many Windows 7 users often need to move OST files into PST format for accessibility, data protection, or account migration. This article explains easy and effective methods to SameTools Convert OST to PST in Windows 7.
Understanding OST and PST Files
An OST file is automatically created when you configure an Exchange, Office 365, or IMAP account in Outlook. It enables users to access mailbox data even without an internet connection. However, OST files are linked to specific Outlook profiles and servers, making them difficult to access independently.
On the other hand, PST files are portable and can be opened directly in Outlook without needing server connectivity. This is why converting OST to PST is often necessary when switching systems, recovering data, or creating backups.
