MSG to OST C# conversion using .NET API without Outlook® or Thunderbird® installed.

How to Convert MSG to OST Using C#

Experience high-speed performance in email processing with Aspose.Email for .NET! It is a C# API that provides developers with a robust set of tools for handling email files without Outlook or Thunderbird installation, including the capability to convert between various formats. Among these capabilities, converting from MSG (Outlook Email Message) to OST (Offline Storage Table) files is a feature that stands out, as it allows a user to store a copy of mailbox information from an Exchange server for offline access.

The integration of individual messages into an offline-accessible mailbox improves application performance through local data access, and assists in maintaining data integrity. Additionally, by having data stored locally in an OST file, users can continue working during server downtime and reduce network load during synchronization. It also simplifies centralized management of email data for organizations, ensuring consistent access across multiple devices.

The email-to-storage-file conversion process with Aspose.Email for .NET is straightforward. The library presents an easy-to-use object model. Converting emails typically requires only a few lines of code, abstracting away the underlying file format parsing, MIME handling, encoding issues, etc. When you use Aspose.Email for .NET, you do not need to manually process any of these aspects. Instead, you write only the high-level code required to perform the task.

Enhance your performance with a comprehensive and easy-to-use API that simplifies complex email management tasks, such as sending, receiving, and processing emails, as well as converting between various email formats. This allows developers to efficiently integrate email functionality into their applications without delving into low-level details, thus significantly reducing development time and effort.

To leverage the power of the .NET API, perform one of the following actions:

  • Open NuGet package manager, search for Aspose.Email and install it on your device.

  • Use the following command from the Package Manager Console:


PM> Install-Package Aspose.Email
