Importing a PST file into BlueMail is not possible directly because BlueMail does not support PST files on its own. A practical method is to use the MacSonik PST Converter Tool, which helps extract data from a PST file and convert it into formats that BlueMail can read. The tool allows you to export PST mailbox items into standard email formats like EML or MBOX, which can then be added to BlueMail by configuring the same email account inside the app. After converting your PST file, you can import the resulting files into your email account, and BlueMail will automatically sync the messages when the account is refreshed. This approach also retains folder structure and attachments, making your PST emails accessible within the BlueMail interface without needing Outlook.
