For those who cannot open their Outlook OST and wish to convert the files into a format that can be viewed on any device, I suggest converting the OST files to PDF. PDF files are accessible across all types of devices (mobiles, laptops, or web browsers) without the requirement of having Outlook installed. In order to perform this conversion, you can utilize an industry-leading tool like DataVare OST to PDF Converter Expert software, which provides users with the ability to convert multiple OST files to PDF while preserving the original folder structure as well as the user-friendly interface. The Demo version allows users to try out the software prior to purchasing the full version.

If you can’t open your OST file, it usually means Outlook can’t connect to the original mailbox or profile it was created from. OST files aren’t meant to be opened directly, so they won’t work on other devices unless you convert them.
The easiest way to make an OST viewable anywhere is to convert it into a portable format like PST, EML, or MSG:
PST → you can open it in Outlook on any system
EML → opens on almost all email apps (Outlook, Thunderbird, Windows Mail, macOS Mail)
MSG → good for saving individual emails
If you just need to access the emails and the original Outlook account isn’t available, you can use an OST conversion tool. A lot of users prefer tools like Stellar Converter for OST because it can open orphaned or corrupted OST files and export them to PST/EML without needing the mailbox.
You just load the OST, let it scan, preview the data, and save it in the format you want. After that, you can view the emails on any device or app that supports those formats.
