To manually Import an OST File into thunderbird, you first need to convert the OST file to a format Thunderbird supports, like MBOX. Since Thunderbird cannot read OST files directly, one manual way is to use Microsoft Outlook to open the OST file and export the emails to a PST format. Then, you can use a third-party tool to convert PST to MBOX. Once converted, you can import the MBOX file into Thunderbird using the "ImportExportTools NG" add-on. However, this process is time-consuming, requires technical expertise, and depends on having access to Outlook.
An easier alternative is to use Cigati OST to PST Converter. This tool allows you to directly convert OST files to MBOX without needing Outlook. It simplifies the process, saving time and effort by providing a user-friendly interface and ensuring no data loss during the conversion. With Cigati, you can efficiently import OST files into Thunderbird hassle-free.
