# How can I convert PST files when Microsoft Outlook is not available?

You can convert PST files even if Microsoft Outlook is not installed on your computer by using a dedicated PST conversion tool. [**PCDOTS PST Converter**](https://pcdots.com/pst-converter.html) is one option that lets you open and process PST files without depending on Outlook. You can add the PST file to the software, preview the mailbox data, select the required folders, and choose the format you want to convert the data into. This can be useful when Outlook is unavailable but you still need to access or migrate emails, contacts, calendars, and other mailbox data stored in a PST file.

## Answers

### Answer by Rowan Fletcher

If Microsoft Outlook is not available, you can still convert PST files using a standalone PST converter. This is useful when the PST is an old archive or needs to be moved to another email platform such as Thunderbird or Apple Mail.\

A simple approach is to use a tool that can read the PST directly, show its mailbox contents, and export the required data without depending on Outlook. You can prefer to use tools like **GainTools PST Converter**, which works offline on Windows and supports PST export to MBOX, EML, EMLX, and MSG. It also provides a preview, so specific folders or items can be selected before conversion.

## Here are the basic steps of the process:

1. **Add PST:** Select the PST file.
2. **Preview Data:** Check the folders and emails.
3. **Select Items:** Choose the required mailbox data.
4. **Choose Format:** Select MBOX, EML, EMLX, or MSG.
5. **Set Location:** Choose the output folder.
6. **Convert:** Start the PST conversion.

This method is useful when Outlook is simply not available, because the PST can be processed independently on a Windows system.
