Hi @hello-chenchen, we plan to get NAA to GA very soon now. We'll also provide more information as we go on either the Office Add-ins community call or the M365 developer blog. Also we will keep updating the sample with any changes that come along. Please take this time to try out NAA and let us know if you spot any issues. You're in the right location to let us know about any issues, or questions you have!

Thanks!
David

[hello-chenchen]

hi @davidchesnut , thank you so much. By the way, can you please take a look and give us some suggestions?

• Does all Office365 users affected? I’m not sure, but as I know Exchange Online is the only Outlook backend service for Office365 users, right? If so, I think this change will affect all office365 users.

• We notice: Exchange 2019 and other on-premises versions of Exchange won’t block legacy Exchange user identity tokens and callback tokens. So, This is how I understand it, please correct me if there is any mistake: For these versions without blocks, we still have only the option is to keep using user identity tokens and callback tokens, right?
