Outlook – View attendees of a meeting which I already accepted in Outlook 2016

I couldn't resolve this within the Outlook desktop client - I tried a huge number of approaches but the event wouldn't budge.

The solution was to log on to my account using Outlook Web Access and delete the event from there. I have no idea what the root cause was, but this was the only working solution in the end!

You can prevent meeting request replies

Even if you don't turn off the response option when you initially send the meeting request, you can change the option at any time.

1. Open the meeting.
2. On the Meeting Ribbon
3. In the Attendees group, click Responses.
   • NOTE: For recurring meetings, the Meeting tab appears as the Recurring Meeting tab.
4. Uncheck Request Responses
5. Click Send Update (It is necessary to click Send Update so that the meeting request is updated in Outlook for all meeting attendees)

According to this article on Understanding Meeting Updates, certain updates must be sent.
