OST to PST Outlook 2019 Converter aka ‘OST Extractor Pro‘ helps you recover and convert data from *.ost file to many other file format.
Microsoft Outlook 2019
Outlook 2019 is the latest version of an email client for Microsoft for Windows. And OST and PST are the data files used by the client, including the previous versions. Some confusion regarding them still exists.
OST and PST
The most common one is the misunderstanding between OST and PST. Both files are used for storing data like emails, contacts, and calendar, but are used in different ways. Unlike OST, PST is much more useful for manual and personal data storage. It is used for importing, exporting, archiving, and backing up data.
Which means that the OST file is an internal file for Outlook. You can get to your emails even without any internet connection. All the changes you make to your data will be synchronized to the servers when you connect to your internet again. This cannot be done through PST files, which are personal files, suitable for backup or archiving or those types of operations.
Therefore, one thing is clear now: if you want to import OST to Outlook 2019, you are going to have to convert it to PST.
