Stellar Converter for OST Review 2024 – Detail Overview, Features & Pricing

Microsoft Outlook stores a local copy of your emails, attachments, and other mailbox items in an OST file. This offline data file allows you to access the mail items, even without connecting to the internet. Sometimes, the OST file becomes inaccessible or orphaned when the profile associated with the file is deleted. In such a situation, you can’t directly extract data from the OST file. The only way is to use an advanced OST to PST converter tool, like Stellar Converter for OST that can extract content from the inaccessible or orphaned OST file. Here, we will discuss all about this tool and see how it works.
