Graph api: ReplyTo not set when sending e-mails

Question

Hello! I am using microsoft graph api to send e-mails. All of sudden, since 1 August, replyTo property is ignored and not set anymore. When the e-mail reaches the destination mailbox, reply-to field is missing from the email header.

This is the body used in the reuqest to send the e-mail:

{"message":{"body":{"content":"test email","contentType":"html"},"from":{"emailAddress":{"address":"test_email","name":"display1"}},"hasAttachments":false,"replyTo":[{"emailAddress":{"address":"test_email", "name": "asdf"}}],"toRecipients":[{"emailAddress":{"address":"test_email","name":"display1"}}]}}

This used to work before 1 August. Is the replyTo field deprecated now?

Thank you!

Seeing the same issue here too. Our application sends mail with the 'replyto' property set. We've seen evidence of the emails being sent without the reply to being inserted into the header for about a week now. We've confirmed using Graph Explorer that graph is sending mail but ignoring the 'replyto' property, so it's not our app that is the cause - it's the API.

I have raised a ticket with MS - case 2408080030000351 - if anyone else has raised a ticket regarding this please post the number here and I'll reply to my ticket with your ticket numbers to try to get some movement at Microsoft HQ...

Same problem here using Graph API, with paid accounts, in our case when creating a draft message defining the ReplyTo field, the response json shows the replyTo correctly, but if the draft message is accessed with another request, the ReplyTo field has disappeared. Using the message update function doesn't work either, it modifies other fields, but not the ReplyTo.

Same here, it worked few days ago, but now it doesn't.

Hi @Furdui, George (FR - External)

After my test, this property is valid, and I set the value of the replyTo property when I sent the email, as shown in the following figure:

Below is the corresponding result for the endpoint that requested to list all messages, and you can see that in the replyTo property, there is a value that was set when the message was sent.

If you set this property does not work, please check whether the email address you set exists or is valid, whether the request endpoint is correct, etc.
