The Microsoft Graph API does not directly support getting mail by
networkMessageId. However, you can use the
internetMessageId to find a message.
Please refer the below links for more information.
Here is an example of how you can make a GET call:
GET /me/messages?$filter=internetMessageId eq '<1430948481468.34600@THCIE7Dev2.onmicrosoft.com>'
Please note that you must URL encode the internetMessageId.
GET /me/messages?$filter=internetMessageId eq '%3C1430948481468.34600%40THCIE7Dev2.onmicrosoft.com%3E'
Remember that the message ID may change if a message is moved or altered.
