How to Efficiently Convert OST Files into MS Outlook PST Files


What is an OST File? 

An OST file (.ost) is a Microsoft Outlook offline storage file that stores information about a user's calendar, inboxes, and other activities. Offline files allow users to work while not being connected to the Exchange server and then synchronize their updates with the server when they reconnect. It is advantageous to be able to operate offline while working in locations with a limited or unstable connection.

What is a PST File? 

An Outlook Data File or a PST is a file that stores all of your emails and other Outlook elements on your desktop's hard drive. Your personal emails are downloaded from your email account to your desktop, where they are stored until you delete them. These files are stored on your device rather than a mail server; they are not susceptible to mailbox space limitations. Transferring things from your email server's inbox to a PST file on your computer allows you to clear up a lot of storage in your mailbox.


Now that you are cleared up on what OST and PST files are, let's see how to convert inaccessible OST files into MS Outlook PST file format to keep your data safe and secure. 

Method 1: 

· Login to Outlook's Exchange account, which you used to create the OST file;
