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!

I'm running into the same issue, where it was working before August 1st. I submitted the following on GitHub -- https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/2613

Same issue here. But I also noticed that this issue only happens when I sent emails with some accounts. I have been testing with Microsoft Graph the following query for https://graph.microsoft.com/beta/users/[ObjectID]/sendMail and posting the body below. When I tried with my own account, the reply to was working as expected (and I could also see the corresponding header in the email that was received) and when I then tried with another account (I signed in with another account in Microsoft Graph) and posted the same body, the replyTo was not found in the email that was received.

    "message": {
        "subject": "Request for Support",
        "body": {
            "contentType": "Html",
            "content": "TEST"
        },
        "toRecipients": [{
                "emailAddress": {
                    "address": "support@xyz.com"
                }
            }
        ],
        "from": {
            "emailAddress": {
                "address": "website@xyz.com"
            }
        },
        "replyTo": [{
                "emailAddress": {
                    "address": "max.demo@xyz.com"
                }
            }
        ]
    },
    "saveToSentItems": true
}```

I get the same issue here using the WPO365 Microsoft Graph Mailer on Wordpress. This just started happening so there must have been something that changed.
