How to migrate Outlook OST to PST?

[alexander]

Many users face difficulties when they try to migrate Outlook OST to PST, especially after an Exchange crash, account deletion, or system formatting. Since Outlook OST files are encrypted and linked with a specific Exchange profile, they can’t be opened or moved directly. To access or restore mailbox data such as emails, contacts, calendars, tasks, and attachments, the most effective solution is to convert OST files to PST format — which can then be easily imported into Outlook.
After trying a few manual techniques, I found that using a professional tool like eSoftTools OST to PST Converter Software makes the migration process much simpler and safer. This software quickly scans any OST file (whether orphaned, damaged, or inaccessible) and converts it into a fully usable PST file without losing a single piece of data. It offers a smart preview feature, lets you select specific folders or items for migration, and maintains the original email formatting, folder hierarchy, and metadata throughout the process.
The best part is, eSoftTools OST to PST Converter doesn’t need Outlook or an active Exchange connection to work. It supports all versions of Outlook — 2021, 2019, 2016, 2013, 2010, and 2007 — and runs smoothly on Windows 11, 10, 8.1, 8, and 7. Once the conversion is done, you can easily import the PST file into Outlook using the built-in Import/Export option.
If you’re searching for a safe, fast, and hassle-free way to migrate OST to PST, I’d highly recommend trying the eSoftTools OST to PST Converter Software. It even offers a free demo version that allows you to convert up to 25 items per folder — perfect for testing before purchasing the full version.
