Stellar Converter for OST Technician licence: not one mailbox at a time, but all the organisation’s mailboxes in a single migration cycle
With the Stellar Converter for OST Technician licence, you can work on an unlimited number of mailboxes.
When a company decommissions an on-premises Exchange infrastructure to migrate to Microsoft 365, or when an organisation needs to recover the mailboxes of dozens of users following an unplanned server decommissioning, the challenge is not converting a single OST file. The challenge is to convert dozens or hundreds of OST files simultaneously, transfer the data directly into Microsoft 365 mailboxes without creating intermediate PST files that need to be managed manually, and ensure that the resulting PST files do not exceed the size limit that causes corruption in Outlook – all in a single operation, without having to open the software dozens of times.
Stellar Converter for OST Technician is designed precisely for this scenario. Compared to the Corporate version, which supports up to 5 mailboxes and produces PST files to be manually imported into Outlook, the Technician version has no limits on the number of mailboxes that can be converted, adds simultaneous batch conversion of multiple OST files in a single process, allows direct export to Office 365 mailboxes and Live Exchange Server without intermediate steps, and includes advanced PST split and compact functions to correctly manage large files. It is the tool for IT administrators, system integrators and MSPs who manage large-scale enterprise migrations, not occasional conversions.

- How does batch conversion work?
Batch conversion allows you to add multiple OST files in a single session and start simultaneous conversion of all of them into corresponding PST files. It is the key feature for enterprise migrations where dozens or hundreds of users have orphaned OST files to convert: instead of processing one file at a time, the Technician version manages the entire set in parallel, drastically reducing operational times.
- How does direct export to Office 365 work?
After conversion, instead of saving a PST file for manual import, you can select Office 365 as the destination, enter the destination account credentials and start the direct transfer. Data arrives in the Microsoft 365 mailbox with the original folder structure fully preserved, without intermediate steps. This feature is available exclusively in the Technician version.
- Why is automatic PST split important?
A PST file exceeding 2 GB in Outlook 2002/2003 or 20-50 GB in later versions may become unstable and corrupted. The split function automatically divides the generated PST into smaller archives, by size (1-50 GB), date or email ID, preventing corruption caused by oversized files and improving Outlook performance.
- Does Stellar Converter for OST Technician support OST files from Microsoft 365?
Yes. The software converts OST files created by Outlook with on-premise Exchange profiles, IMAP and Microsoft 365, including orphaned OST files after a Microsoft 365 account has been decommissioned.
- Can the Technician license be installed on multiple PCs?
The standard Technician license is for a single device. However, Stellar offers Bulk Licensing for Technician editions: licenses can be purchased for 1, 5, 10, 25, 50, 100, 200 or 500 devices, ideal for MSPs and IT departments managing multiple migration workstations.
- When should you NOT choose the Technician version?
If you only need to convert up to 5 mailboxes without requirements for batch conversion or direct export to Office 365, the Corporate version is sufficient at a lower cost. If you need a complete suite including PST repair, archive merging, deduplication and other Outlook tools, consider the Toolkit version.
