How Do I Convert OST to PST Without Outlook?

Last updated on April 3rd, 2023

OST and PST both terms denote the storage format of Outlook, which is one of the most reliable email clients nowadays. PST files stores Outlook data in the local drive and can synchronize with the different servers except for Exchange Server. In contrast, OST allows Outlook users to work offline and synchronize with the exchange server to make changes when the internet connection gets re-established. However, sometimes, users need to convert OST to PST without Outlook to synchronize their data with different platforms or create an OST file backup.

This write-up will demonstrate all the possible ways available for OST file conversion into PST format without Outlook.

Is it possible to convert OST to PST without Outlook?

Before answering the question, let me mention the types of OST files. Yes, OST files have two types, and most users don’t know this. These two types are as follows:

Orphaned OST files: These OST files are disconnected from Exchange Server, or users have deleted the Outlook profile of this OST file. The problem with orphaned OST files is that users cannot access them or convert them manually, even with Outlook.

Exchange OST files: These are the OST files connected with the Exchange Server; users can easily access and use these OST files. To convert these OST files, Outlook offers several inbuilt utilities. But if you’re looking to convert them without Outlook, then there is no method available.

So by understanding the OST files types, it is clear that users cannot convert OST to PST without Outlook or with Outlook if they are orphaned. You have to opt for a third-party OST to PST Conversion tool.

Can we open the OST file with other users’ profiles?

Actually, you can’t; OST files are tied with a specific MAPI profile, and if you try to open them with the other user’s profile, Outlook will refuse. This is because OST files stores an encrypted cookie generated from the Outlook profile’s unique ID. And every time you work in offline mode, Outlook matches the OST files cookie afterward, and if it can’t find the cookie, then Outlook will refuse to make any changes in OST, and there are possibilities that your OST will get corrupt.

The thing is, you can’t convert OST files without Outlook manually, whether they are healthy or in an orphaned state. Therefore, a third-party OST to PST converter tool is necessary to access your OST files in PST format or move them into your new profile or email client.
