Stellar OST to PST Converter vs Other Leading Solutions: A Comparison of 6 Conversion Tools

Introduction

Microsoft Outlook users often encounter scenarios where OST files become unreachable due to issues with the Exchange server, corrupted profiles, accidental disconnection of accounts, ongoing synchronisations, or the need to migrate mailboxes. Therefore, converting the offline mailbox information into a convenient Outlook file format is crucial for restoring email access and ensuring business continuity.

Although Stellar is recognised in the industry, a lot of professionals are looking for other options because of varying prices, required features, licensing options, export abilities, or user interface preferences.

This article reviews six popular mailbox repair and Outlook migration software that can be used instead of Stellar. We study their advantages, disadvantages, possible benefits, and overall worth.

What is OST to PST Conversion?

The acronym OST refers to an Offline Storage Table, which is a local copy of the mailbox that Microsoft Outlook creates when the application is linked to an Exchange Server, Microsoft 365, or Outlook.com account. An OST file gives access to emails, contacts, calendars, tasks, and attachments when there is no Internet connection available.

To put it in simple terms, PST refers to a Personal Storage Table that stores Outlook information for any backup, migration, archiving, or transfer.

The process of conversion refers to extracting the information from the mailbox stored in an OST file and converting it into a PST, a type of file that Microsoft Outlook can read on any computer or with a different profile.

Some of the data that can be recovered into a new file include:

• Emails
• Attachments
• Contact details
• Calendar information
• Notes
• Tasks
• Journals
• Folder hierarchy
• Metadata

Why is OST Mailbox Recovery Important?

Mailbox conversions take place for several reasons:

• The original Exchange server is inaccessible in some cases, rendering it necessary for users to extract data from a mailbox using a local copy of it.
• With Outlook profiles damaged, accessing mailbox contents becomes impossible.
• Some organisations preserve employees’ mailboxes for lawful reasons.
• Some organisations migrate to new systems only if mailbox formats are convertible.
• The process of extracting data from a mailbox can make a strong base for data backup.
• Certain sectors require keeping emails for a long time for audit purposes.
