For most IT admins, moving Outlook data to Microsoft 365 is one of those tasks that seems easy on paper but turns out to be a headache in practice. PST files are huge, OST files are stranded on decommissioned servers and one network hiccup can mean redoing an hours-long job. Softaken Software developed its PST to Office 365 Importer to correct that experience, and Version 2.0 takes it further than ever.
Unlike generic import utilities, Softaken’s tool connects directly to Microsoft 365 using the official Graph API and is authenticated via OAuth 2.0. No passwords stored on disk, no unsupported workarounds that break after a Microsoft update, and no dependency on a live Exchange server. The tool works perfectly if the old mail server is no longer around — it reads directly from PST and OST files on disk.
Version 2.0 also adds support for IMAP servers into the mix, meaning admins can pull mail from any standards-compliant mail server and land it in a Microsoft 365 mailbox. Combined with full migration of emails, contacts, calendars, tasks and sticky notes, it has everything a business needs to migrate in one go.

What makes this release stand out:
• Crash-proof checkpointing – folder progress is continuously saved so interrupted jobs pick up exactly where they left off
• Duplicate detection – an idempotency store prevents re-runs from creating duplicates in the target mailbox
• Flexible folder mapping — choose to retain the original structure, flatten it or route everything to a new folder
• Smart attachment handling – a dual-lane system allows large files to not bottleneck the rest of the queue
• Clear reporting – you get an HTML report after each run that tells you exactly what moved, what failed.
Pricing is per source file, not per message, so it’s easy to budget for a migration project up front. A free trial is available at https://www.softaken.com/pst-to-office-365-importer.

“An admin’s life should be easier, not harder, if they’re using a migration tool,” said a Softaken spokesperson. That is the standard we set for ourselves with every decision in Version 2.0
