How to Import OST File to Thunderbird
To Import an OST file to Thunderbird manually, you need to convert the OST file into a format supported by Thunderbird, such as MBOX or EML. Unfortunately, Thunderbird does not support OST files directly, as OST files are linked to Exchange Servers or Outlook accounts. A manual method involves using Outlook to first convert the OST file to PST, and then using an additional tool like "ImportExportTools NG" to import the PST file into Thunderbird. This process can be lengthy, requires access to Outlook, and might risk data loss if not handled carefully.
