message resource type
Namespace: microsoft.graph
A message in a mailFolder.
The maximum total number of recipients included in the toRecipients, ccRecipients, and bccRecipients properties for a single email message sent from an Exchange Online mailbox is 500. For more information, see sending limits.
This resource supports:
- Adding your own data as custom Internet message headers. Add custom headers only when creating a message, and name them starting with "x-". After the message is sent, you cannot modify the headers. To get the headers of a message, apply the
$selectquery parameter in a get message operation. - Adding your own data as custom properties as extensions.
- Subscribing to change notifications.
- Using delta query to track incremental additions, deletions, and updates, by providing a delta function.

If ispopout is not present or if it is set to 1, then the message is shown in a popout window. If ispopout is set to 0, the browser shows the message in the Outlook on the web review pane.
