Mail Message api not returning messages thread.

Question

Dear Concern,

I am using Microsoft graph mail API and fetching message by this api https://graph.microsoft.com/v1.0/me/messages/{id} but is not giving thread messages.How can I get thread replies of inbox message.

Answer 1

The https://graph.microsoft.com/v1.0/me/messages/{id} endpoint your using will only return the Message with that particular Id. To get all the message within a particular thread you would need to use a Filter on the Messages Collection based on the CoversationId property of one of the Messages in that thread eg

/Messages?$filter=conversationid eq 'Message.ConversationId'

or

/Messages?$filter=conversationid eq 'Message.ConversationId'&$orderby=receivedDateTime desc

If you want them ordered by last received where Message.ConversationId is the conversationId from the Message
