Easily Convert Encrypted OST Files Into PST With Stellar Converter For OST

OST and PST are two types of data files used by Microsoft Outlook to store emails, contacts, and other data.

OST (Offline Storage Table) is an offline copy of your online mailbox data that’s stored on your computer. It allows you to access your emails, even when you’re not connected to the internet. OST files are used for email accounts that are configured with Exchange or IMAP server. OST files are attached to the account in which they’re created. You cannot open or migrate OST files to any other account. 

PST (Personal Storage Table) is a file that contains all your Outlook data. PST files are used for email accounts that are configured with POP3. You can also use it to back up your Outlook data or to transfer it to a new computer.

As the OST file is not transferable to another Outlook account, you need to first convert it into PST file. You can use the Outlook options to save OST data into PST but it can only work if Outlook is working and OST file is accessible. If Outlook is not working or OST file turned inaccessible or orphaned, you need to use a specialized OST to PST converter tool.
