'Reading singleValueExtendedProperties of an email attachment

I have an email message which has another email message as an attachment.

I am trying to read the singleValueExtendedProperties of the attached email message using below query, but it doesn't work.

I don't see singleValueExtendedProperties in the response.

https://graph.microsoft.com/v1.0/users/{mailbox}/mailFolders/Inbox/messages/
{messageId}/attachments/{attachmentId}?$expand=microsoft.graph.itemattachment/
item($expand=microsoft.graph.message/singleValueExtendedProperties(
$filter = id eq 'string 0x001A'))

According to the documentation, singleValueExtendedProperties are not available at mail attachment level.

Supported resources for singleValueExtendedProperties are:

  • calendar
  • contact
  • contactFolder
  • event
  • mailFolder
  • message
  • group calendar
  • group event
  • group post

When an email message with singleValueExtendedProperties is attached to the another email then singleValueExtendedProperties are lost.
