RSVP action has no effect


Clicking on the RSVP action in an e-mail invitation has no real effect, apart from the visual change of the status in the invitation e-mail. That is, if I click “Accept”, I see the “Accept” button turning green, but in the actual calendar event, there is no reply. This happens with Microsoft Teams invitations sent to my Microsoft O365 account.

To Reproduce…

Get an invitation to an MS Teams event (or to any other Microsoft O365 shared calendar event), click on the RSVP inside the e-mail invitation and check whether the reply is synched with the actual event.
(PS: I could only attach one screenshot)

Expected Behavior

The RSVP reply should be synched with the calendar shown in Teams/Outlook
