Stellar Converter for OST is a powerful email management utility that can help professionals and businesses to extract inaccessible OST files (offline folder files) in Microsoft Outlook and convert them into easily accessible Outlook PST files (Personal Folders file that contains local copies of Mailbox content).

  • Converts orphaned, encrypted, or IMAP OST into PST
  • Supports Outlook 2021, 2019, 2016, and earlier versions
  • Exports OST file data to Office 365, MS Outlook, and live Exchange (Technician Plan)

Built from the ground up to be capable to work with large OST and PST archives, this enterprise-grade application can quickly, easily, and reliably convert encrypted or orphaned OST files. It features full support for all the latest versions of the Outlook app (2021, 2016, 2016, and even earlier versions), and has a built-in converter for exporting all recovered data to Office 365, MS Outlook, and live Exchange.

OST file is a temporary backup that Microsoft Exchange keeps for every connected user and their mailbox. It contains all data associated with that account, which includes local copies of messages, calendar events, and many other items. This archive is accessed and updated when users are working on their account offline, with Exchange service synchronizing newly added data with live content on cloud servers when the internet connection is established. However, if a user's Mailbox is deleted or corrupted before an active backup is made, the only way to regain access to mailbox data is by recovering and converting the OST archive.

Stellar Converter for OST performs this activity reliably and quickly, enabling teams, companies, and organizations of all sizes to export OST into PST, and manage PST with an advanced “8-in-1 solution” Stellar Toolkit utility that provides tools such as merging, splitting, partial deleting, and exporting. Users even have the ability to merge multiple OST files into a single PST.

To accelerate the procedure of recovering data from OST archives, Stellar Convert OST to PST can automatically locate and list Outlook data files, provides previews for all found local files, built-in search engine, auto splitter of large PST archives, and many other extraction, conversion, sorting, and filtering tools. The advanced Technician licensing tier even allows for direct exporting of multiple mailboxes from OST and PST archives into Office 365 accounts, both individually and as a batch processing procedure. The most expensive “Toolkit” license tier can even recover lost Outlook passwords and attempt recovery of deleted emails.
