How to get item.Headers.Item("In-Reply-To").ToString in get mail Microsoft 365

Hi @sathish_Kumar6

So …you want to know if a message is replied or not… there is no direct way but you can try this… from get mails once you get your inbox …and getting the mail you can get the unique id of the mail and then use get mail from sent items and then match the id for this your in-reply-to in header will help to match.thats not straight but give it a try

Cheers
