eSoftTools offers a free OST to PST converter software that retrieves and converts emails and their attachments. The software enables the extraction of calendars, contacts, and other OST file contents before converting it to PST.

What I love most about this Free OST to PST Software is its ability to not only remove errors but also repair damaged OST files and convert them to PST format with ease. With this software, users can recover selective single and multiple folders from OST files and convert them to PST with contacts, calendars, task, notes, inbox items, outbox items, journals, notes, and other mailbox items.
The Free OST Converter Software is also able to convert OST to PST Free, MSG, EML, EMLX, MBOX, vCard, and HTML formats, making it a versatile tool that can handle different file formats. Another great feature of the software is that it doesn't require MS Outlook installation or exchange server installation to perform the conversion.
Users can also rest assured that their emails and attachments are safe and that the software maintains every email's formatting and attachments during the conversion process. Additionally, the software performs well with encrypted password-protected OST files for recovery and conversion.
The Free OST Converter Software supports all MS Outlook versions, including 97, 2000, 2002, 2003, 2007, 2010, 2013, and 2016, which makes it accessible to many users. The free trial demo version also allows you to save 20 emails per folder into every format, which is a great way to test the software before purchasing it.
Overall, I recommend this software to anyone needing to convert an OST file to PST format. It is reliable, efficient, and easy to use, and the full license purchase is well worth the investment for those needing to convert and restore all data of their OST files.
