Introduction

Email management is a crucial part of personal and professional communication. For Microsoft Outlook users, converting OST (Offline Storage Table) files to PST (Personal Storage Table) files is necessary when migrate accounts, recovering data or managing backups. This guide will take you through the process step by step, with clear explanations and tips.

What are OST and PST Files in Outlook?

OST Files

OST files allow you to access emails, calendars and other data offline. These files are created when using Outlook with Exchange Server, IMAP accounts or Office 365. But they are not portable across different systems or profiles so conversion to PST is necessary in certain situations.

PST Files

PST files store emails, calendar events and tasks on a local drive. They are portable and can be imported into Outlook on any system so they are perfect for migrations or backups.

Why Convert OST to PST?

There are several situations where OST to PST conversion is necessary:

Recover Data from Inaccessible OST Files: If an Outlook profile becomes corrupt the OST file becomes inaccessible. Converting it to PST will help you retrieve your data.

Migration to a New System or Account: When moving Outlook data to a new device or email account PST files are the best way to transfer data.

Backup and Archival Needs: PST files are a convenient format for long term storage of emails and data.

Server Downtime: Converting OST files will allow you to access your important data during server outages.
