What do you think about RSVP in Outlook?

HI KimT555 

"never send a tentative or decline without a note"
Good to know and noted . We are currently exploring some changes to the design/flow of adding notes on Outlook on the Web and the New Outlook for Windows. The vast majority of the time, users do not need to add a note (e.g. when accepting the invite), but when they do it is very important. So it might be useful to make the note field a little less evident to not take up so much space all the time for everyone, but still keep it easily accessible at a click for those users that sometimes need to use it. 

"tracking happens regardless of if a response is sent ... when RSVP'er and the Host are on the same version"
We also refer to these as "silent responses", when no visible response message/email renders on the organizer's Inbox. I know there is still a lot of improvement opportunities for silent responses. We are currently investigating them, with a special attention to scenarios involving cross-client (i.e. organizer and attendee in different Outlook apps), cross-tenant (i.e different companies) and cross-platform (i.e. different products).

"declined meetings can still show in the calendar"
We finally delivered this in Nov 2023, and it has been a great success. And we have more coming soon in this line of preserving/keeping things instead of deleting/removing. If you don't like your invite emails disappearing from your Inbox after you RSVP, we've got a new setting already in internal testing for you: "Do not delete invitation after responding".  

Thank you for taking your time to share your feedback, KimT555.  I will remember you for more feedback when time comes.
