How to Extract Email from OST File?

Summary: Outlook stores emails in an Outlook data file, such as OST or Offline Folder, which is encrypted by default with MAPIEntryID GUID key. Thus, it requires authentication from the linked MAPI profile to access or extract and export the emails. In this guide, we help you access, read, and extract emails from OST file. We also mention an OST to PST converter that can extract emails from inaccessible or orphaned OST file.


How to Extract Email from OST File?

To extract emails from the active OST file, you can export the emails from Outlook via Outlook Import Export wizard to PST files. Unlike OST (Offline Folder), you can import the exported PST (Personal Folder) file (containing emails and other mailbox items) into any Outlook profile, live Exchange mailbox, or Exchange Online (Office 365). You may also drag and drop an email into a folder and save each individual email as .eml (email) file.

However, if the OST file is not accessible or the Outlook profile is corrupt or deleted and you can’t access Outlook, then it is not possible to extract emails from OST file to PST via Outlook Import Export wizard. In such situations, an OST to PST converter software, such as Stellar Converter for OST, comes in handy. Besides PST, the software also allows you to save individual emails in EML, MSG, HTML, PDF, and RTF formats. Thus, you can open the extracted emails through various applications, such as a web browser, text editor, etc.

In this guide, we’ll discuss the methods to extract emails from OST file to PST and other desired formats.
