The PST file (Outlook Personal Storage File) is a proprietary file format used by Microsoft Outlook to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook. The PST file acts as a local archive, allowing users to manage their email data offline, organize their email inbox, and back up important correspondence, contacts, and calendar appointments. It can be password protected for added security.
The EMLX file format is implemented and developed by Apple. The Apple Mail application uses the EMLX file format for exporting the emails. There are other applications as well that can open the EMLX files and convert these to other file formats.
