OST to PST Migration Software: Comparative Analysis of 5 Tools

OST files are a vital part of Microsoft Outlook, which allows users to access their mailbox information even when there is no internet connection. However, there are instances when users need their mailbox data in PST format for backup, migration, recovery, or account transfer needs.

For example, OST to PST conversion is required if a business switches to a new Outlook profile, restores data from an orphan OST file, or creates long-term email archives.

There are so many conversion tools available in the market that choosing the proper solution might be a headache. Some tools are straightforward, others are focused on recoverability and batch transfer or complex exporting choices.

This comparison evaluates five OST to PST Converter solutions:

• TrustVare OST to PST Converter

• MailDaddy OST to PST Converter

• FreeConverter.app

• Regain OST to PST Converter

• eSoftTools OST to PST Converter

The aim is to see how these tools compare against the core migration requirements and allow users to choose the best fit for their needs.

Understanding OST and PST Files

Before we go into the software comparison, it is vital to know the difference between OST and PST files.

What is an OST File?

OST (Offline Storage Table) is an Outlook data file that stores a synchronised copy of mailbox data from Exchange Server, Microsoft 365 or IMAP accounts.

The main feature of the OST file is to allow users:

• Read mail offline

• Work offline without a network connection

• Re-synchronise mailbox updates on re-connection

• Keep copies of mail in your local mailbox

But, normally OST files are related to a particular Outlook profile and account.

What is a PST File?

PST (Personal Storage Table) is a portable Outlook data file that is used to:

• Backups of email

• Archiving of mailboxes

• Migration of data

• Outlook export and import

• Long-term email archive

PST files are easily transferable between Outlook profiles and platforms, unlike OST files.

Why Is OST to PST Conversion Important?

There are various situations when OST to PST conversion holds importance:

• If you delete the original Exchange account, you might not be able to access the OST file. It assists in mailbox data recovery when converted to PST

• Profile damage can also leave a mailbox's contents inaccessible. PST conversion is an alternative way of getting information.

• OST to PST conversion is done by organisations for backup and retention needs

• Companies migrating from one Exchange environment or Microsoft 365 tenant to another often need PST files.

• An organisation can archive the mailbox data in PST format before deactivating an employee’s account.

• PST files are often used for long-term preservation and eDiscovery.
