How to retrieve message using message Id?

How to retrieve message and save in the disk (msg format) using message Id using Aspose.Email using C# without reading whole PST file?

Hi Sumit,


Thank you for writing to Aspose support team.

You can use the PersonalStorageQueryBuilder class object to search for the message using the message id. Once the results are available, the message can be extracted directly and saved to disc without searching the whole folder. The following example demonstrates how to achieve this. Please feel free to write to us if you have any additional query/inquiry in this regard.

Sample Code:

PersonalStorage pst = PersonalStorage.FromFile(“SomePstFile.pst”);<o:p></o:p>

FolderInfo folder = pst.RootFolder.GetSubFolder("Inbox");

PersonalStorageQueryBuilder builder = new PersonalStorageQueryBuilder();

builder.MessageId.Equals("some message id"); //input the message id criteria

MessageInfoCollection messages = folder.GetContents(builder.GetQuery());

MapiMessage mapi = pst.ExtractMessage(messages[0]); //Save the mapi message extracted

Hello sir, thank you for reply.

but when i applied builder.MessageId.Equals(“some message id”);
it is giving me error like “pst searching engine does not support “MessageId” as field name”.
Can you please help me to find out solution?
