I am currently using Microsoft Outlook with an Exchange account, and all my mailbox data is stored in an OST file. Due to a server issue and account deactivation, I can no longer access Outlook, but I urgently need my emails in EML format for backup and to open them in email clients like Thunderbird or Windows Mail. I tried copying the OST file, but Outlook does not allow direct export from OST to EML. Is there any reliable way to convert Outlook OST files to EML format, especially when Outlook is not accessible? I am looking for a solution that preserves email formatting, attachments, and folder structure.
