New Delhi, India – August 22, 2026 – DataVare, a developer of email migration and file conversion software, today announced the launch of its DataVare OST Converter, which provides users with an organised way to convert and recover Outlook offline mailbox data.

OST files store emails, contacts, calendars, tasks, diaries, notes, and folders that you use while working with Microsoft Outlook. Having several output options can add flexibility to the process when users want to migrate this information into another storage format or prepare it for a different email environment.
It helps to convert a wide range of files such as PST, MBOX, Lotus Notes NSF, TGZ, EML, EMLX, MSG, HTML, MHTML, PDF, IMAP and many more. This means that users can choose an output format that fits their specific email migration or data management needs.

Outlook Offline Data Multiple Output Options
The key factor while dealing with OST files is the destination format required after the conversion. Users need their mailbox details for Outlook migration, another email platform, document access or long-term storage.

The software allows users to choose from a variety of destination formats instead of constraining them to a single conversion method. This covers PST with Outlook compatibility, MBOX, EML, MSG, HTML, MHTML, PDF and others.
The multi-format method allows users more flexibility when planning how to save or access their offline mailbox information.

Processing Multiple OST Files in Bulk
Dealing with several offline mailbox files individually can add to the manual effort of a migration project.
The batch migration feature enables users to import and convert numerous OST files at a time. This capability is for high-volume processing and can help minimise some of the tedious work of having to deal with several source files.
If your firm has multiple employee mailboxes or larger email archives, batch processing can give a more structured way to convert files.

Retain the Original Mailbox Structure
Along with the content of an email, the structure of a mailbox also holds significance. Messages are commonly organised into folders and subfolders by project, department, client or other categories.

The conversion procedure is arranged to preserve the original hierarchy of the mailbox, including the organisation of folders and subfolders. This helps to retain the organisational structure you are acquainted with in the generated data.
Keeping this structure helps facilitate navigation and review of converted email records.

Filter Emails by Time Range
No need for a whole mailbox for each conversion project. Sometimes users need messages from a particular time period for an audit, compliance, project review or timeline archiving.

Users can target email datasets from a given period with the built-in date range filtering feature. This allows a more selective approach to processing, rather than having to include every message in an OST file.
Thus, date-based selection might be advantageous when users are working with targeted email data sets.

Use Custom Naming Conventions
When you have plenty of converted files to deal with, it can be challenging if the output names aren't consistent.

The software allows for customisable naming conventions, enabling users to employ established name forms or to build their own. This will make it easier to identify, organise and handle exported email files after the conversion process.
Consistent file names can also make future review and storage more structured in larger projects.

Designed for Conversion of Organised Outlook Data
Managing offline Outlook data is rarely as simple as changing a file extension. Some users can look for a proper destination format, multiple source files, maintaining the mailbox structure, or separating email data from a specific time period.

A structured conversion workflow can help to meet these needs by combining file selection, batch processing, filtering, naming, preview and conversion monitoring into one procedure.
Users can choose from numerous output formats to suit their needs when preparing mailbox information for Outlook migration, cross-platform access, document-based storage, or other email management procedures.
