Description

Is your feature request related to a problem? Please describe the problem.

I am trying to get the internetMessageHeaders for every email in the mailbox. I noticed that for emails that are send - the API doesn't return this if you make https://graph.microsoft.com/v1.0/me/messages/messageId?$select=internetMessageHeaders. The only workaround that I've think of so far is to get the message as a stream https://graph.microsoft.com/v1.0/me/messages/messageId/$value and I parse it with MailKit MimeKit.MimeMessage.LoadAsync(messageStream)

Describe the solution you'd like.

I would like the prop internetMessageHeaders to work also for send emails but not only for received.

Additional context?

Research direction

Start by reproducing the Microsoft Graph request to /me/messages/{messageId}?$select=internetMessageHeaders for both received and sent messages, then review the issue comments for any scope or ownership clues. Done means sent messages return internetMessageHeaders through the SDK/API, or the limitation is documented if the behavior is outside this repository.
