If you’re looking for an easy and efficient way to convert OST to Maildir format, this guide will provide step-by-step methods to accomplish the task. Go through this article till the end to know the complete process.

OST (Offline Storage Table) files are used by Microsoft Outlook to store mailbox data when working offline. However, these files are not directly accessible without Outlook, making it difficult to migrate or access emails on different platforms. On the other hand, Maildir is a structured email format commonly used on Linux-based mail servers, providing a more organized way to store and manage emails.

Converting OST to Maildir can be useful for users who want to migrate emails to a Maildir-supported server, create a backup in a different format, or access emails independently of Outlook.

Since there is no manual method available, the only option is to use an automated tool. OST and Maildir are completely different file formats and cannot be converted directly. However, an automated tool can easily handle this complex task without any issues.
