Quick RSVP email organizer has disappeared.

Hi All,

I’ve run into a problem on my work email where the “email organizer” button has disappeared. For reference this is what it used to look like.

It’s somehow minimized the RSVP box so my options are now accept, decline, or follow with no option to email the organizer. It’s turned into every email I RSVP to sending a replied response which it incredibly frustrating.

I’ve searched everywhere trying to find a solution with no luck. Does anyone have any suggestions?
