Aspose MSG Metadata Utility

I have a batch of Outlook MSG files whose header information—limited to the sender, recipients, subject, and date—must be programmatically controlled with Aspose.Email. The end result should let me open any given MSG, surface those four fields cleanly, change them when required, and save the file back without corrupting its structure.

Key points you should know
• File scope: Outlook MSG only; no PST, OST, EML, or MBOX handling is needed.
• Metadata scope: sender, recipients, subject, date. Nothing else has to be touched.
• Library requirement: Aspose.Email must be the engine that reads and writes the data so licensing-related code samples are expected.

Deliverables
1. Source code (preferably C#/.NET, but I am open to your language of choice as long as it works with Aspose.Email).
2. Ensure Metadata is clean
3. A short test demonstrating that a modified file still opens perfectly in Outlook with the updated fields and Metadata intact.

I’ll test with a small set of real mail items and sign off once the metadata reads back exactly as written. If anything is unclear, let me know and we can fine-tune before you start coding.
