How to Read Email Messages from Microsoft SharePoint Document library

This technical tip explains how to read email messages from a Microsoft SharePoint document library. To access files in a SharePoint document library, the SharePoint SDK must be installed on the system. The SDK provides the API necessary to log in and access files from the document library. The programming samples below assume that a Microsoft Outlook Message file (.msg) is already stored in the SharedDocument folder of the SharePoint Document Library. The SharePoint SDK is used to get the message file into a stream and then pass this stream to an instance of Aspose.Email's MailMessage class. The MailMessage class loads the stream and parses the Outlook message file. After that, access the MailMessage class' properties, for example, subject, text body, HTML body etc. to use the information in a Visual Studio project.
