In this step by step tutorial, we’ll explain how to save email message to disk in C#. The email message can be saved as EML or MSG file formats on the disk. We’ll be getting messages from Exchange email box, however you can get messages from other mail boxes as well and save to disk.

Steps to Save Email Message to Disk in C#

1. Get Aspose.Email for .NET package from NuGet.org
2. Include Aspose.Email.Clients.Exchange and Aspose.Email.Clients.Exchange.WebService namespaces
3. Set license with the help of SetLicense method
4. Provide Exchange Server account information
5. Create an object of NetworkCredential class
6. Create a new Exchange client object of EWSClient Class
