Export Selective Mailbox Items and Folders from OST to PST
When handling OST files, you may not always need to export the entire mailbox. In many cases, extracting only selected emails, folders, contacts, or calendar entries is a more efficient approach. Selective export minimizes file size, removes irrelevant data, and helps keep the resulting PST file structured and easy to manage. Large attachments, junk emails, or irrelevant data can make PST files unnecessarily bulky, increasing the risk of corruption and slowing down performance. By exporting only what you need, you can maintain efficiency and avoid common issues associated with oversized or unfiltered PST files.
However, Outlook’s built-in export options offer limited flexibility and don’t support granular filtering. That’s where EdbMails OST to PST Converter steps in. It allows you to selectively export content based on criteria like date range, subject, sender, or specific folders, giving you the control that native tools lack.

With a straightforward, step-by-step interface, EdbMails makes selective OST export simple and precise. Whether you're handling a large mailbox or targeting only a portion of your data, the tool ensures a seamless export process while preserving data integrity throughout.
This feature can be beneficial in many real-time scenarios, such as:
- Exporting Specific emails: At times, exporting the entire OST file isn’t necessary, especially when you're only looking for emails tied to a certain project, sender, or time frame. EdbMails makes this simple with its built-in filter options, allowing you to define custom criteria like date range, sender name, subject line, or even attachments. This way, you can extract just the emails you need and avoid exporting unnecessary data.
- Exporting Specific Folders: Your OST file might include various folders like Inbox, Drafts, Sent Items, and custom folders, but you may only want to export certain ones to PST. EdbMails lets you pick the folders you need, making it easier to manage storage and keep things organized. This is especially helpful when you want to skip folders like Junk Email or Conversation History.
- Exporting Specific Items: In addition to exporting specific emails or folders, you may need to retrieve and export only specific mailbox items such as contacts, calendar entries, or tasks from an OST file to PST. With EdbMails, you can select the required items based on your requirements and export them to PST.
- Removing Unwanted Items: Sometimes, your OST file might contain unnecessary items like duplicate messages, junk mail, or emails with oversized attachments. EdbMails allows you to apply filters to skip these during export, helping you create a well-organized PST file that’s ready to use in Outlook.
