List-Unsubscribe header in Microsoft Graph Api is not working












0















I have added unsubscribe header while sending email via Microsoft Graph API but still it is not adding List-Unsubscriber header in the email.



Dim HeaderOptions = New List(Of [Option]) From {
New HeaderOption("List-Unsubscribe", "<mailto:unsubscribe@example.com?subject=unsubscribe>"),
New HeaderOption("priority", "High")
}

graphClient.Users(FromEmail).SendMail(objMessage, True).Request(HeaderOptions).PostAsync().Wait()

  • Please read Under what circumstances may I add “urgent” or other similar phrases to my question, in order to obtain faster answers? - the summary is that this is not an ideal way to address volunteers, and is probably counterproductive to obtaining answers. Please refrain from adding this to your questions.

The header options that you are using are intended for adding HTTP headers to the HTTP request. I believe the header you are trying to add is actually an Email message header. To add these you should use the InternetMessageHeaders property on the Message object itself.

  • Interesting. That seems broken to me. I'll see if I can find the right person to talk to about this. According to this iana.org/assignments/message-headers/message-headers.xhtml there should be no x- prefix.

  • @SheerazAhmed I followed up internally on this and unfortunately, someone chose to disallow adding headers without the 'x-' prefix. I am working to get this resolved.
