Hello,
We have been trying to run a program in C# that sets up voting options in Outlook email using GraphAPI. But the email is getting sent without the voting options.
Have you worked on a way to add voting options programatically using C#? This is impacting our development of this particular function of providing voting option.
Any quick response will be very helpful.
Welcome to our forum!
Looks like your issue is related to Graph, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client and we will remove "office-outlook-itpro" tag .
Thanks for your understanding and hope your issue would be resolved soon.
To include voting option in your mail you can use single-value extended property
Extended properties allow storing custom data and specifically serve as a fallback mechanism for apps to access custom data for Outlook MAPI properties when these properties are not already exposed in the Microsoft Graph API metadata.
To use Single-value extended property you can Refer to this documentation
Further you can refer to these similar post-

Hope this helps.

We had tried this option but couldn't get it working.
Can we get any pointers to C# sample for sending mail with voting option?
