Microsoft Outlook is a widely used email client that features a proprietary file known as the OST (Offline Storage Table), which contains a duplicate of the mailbox data in Outlook. In addition to storing emails, contacts, calendars, tasks, & other data on the local system, a PST data file is also referred to as a personal storage table. An email client that is open-source & cross-platform, Mozilla Thunderbird offers data in either MBOX & Maildir file formats. A mailbox can only be inserted into Mozilla Thunderbird by converting PST/OST files to MBOX. OST/PST files can be exported from a Thunderbird mailbox using the BLR Outlook Convert Toolkit. Some users are able to obtain this software in any Windows OS edition easily. Within a few simple stages, the BLR Outlook OST/PST File Converter can import OST data files directly into Thunderbird. As a result of its simple and intuitive user interface, the conversion can be executed by any user without any data loss. It also maintains a record of all email data, including attachments and other data, in the same manner as before.
