Converting a DBX file to PST can be done in two ways: manually or using automated software. The manual method has drawbacks, such as requiring Outlook Express and MS Outlook to be installed on the same PC, and it can be time-consuming, especially with many files. So, I suggest using a professional tool like XConverter Pro DBX to PST Converter. This software can easily convert DBX to PST and offers additional features like exporting DBX files to EML, Exchange Server, and Office 365.
