Steps to View OST via C#
Aspose.Email makes it easy for developers to view OST files with just a few lines of code.
- Open the OST file using the PersonalStorage.FromFile method.
- Create the output directory if it does not exist.
- Get the Inbox folder using RootFolder.GetSubFolder(“Inbox”) to locate the Inbox folder in the OST file.
- Iterate through messages in the Inbox using inbox.EnumerateMapiMessages() to loop through all the messages in the Inbox.
- Configure HtmlSaveOptions to save resources (like images) to files using relative paths.
