BlueMail doesn’t support PST files by default, so you can’t import them straight into the app. To work around this, you can use the MacSonik PST Converter Tool to extract your PST data and save it in formats like EML or MBOX, which email clients can easily read. Once the PST data is converted, simply configure your email account in BlueMail, upload the converted files to that account, and BlueMail will sync the messages automatically. This way, all your PST emails—including attachments—appear inside BlueMail without needing Outlook.
