Send updates only to added or deleted attendees in new outlook

I checked the deployment status, and this change is out worldwide so everyone should have it now. I created a test meeting with a few recipients and then a few minutes later opened the meeting and added one more recipient, clicked Send and I got the prompt.

There are some exceptions where you will not get the prompt, Send Update to Attendees prompt not displayed when updating meetings - Outlook | Microsoft Learn.

• Any of the following are true:
  • No attendees respond to the meeting.
  • The organizer cancels the meeting.
  • The organizer selects Response Options > Request Responses for the meeting.
  • All the meeting attendees are group mailboxes.
  • A delegate receives a copy of the meeting message on behalf of the attendee.
  • The organizer changes meeting options that are full updates, such as the subject, start time, end time, location (including adding, removing, or changing a room), recurrence, time zone, do not forward, hide attendee list, or sensitivity labels.
  • The organizer changes organization settings that affect meeting updates.

When will this be fixed at 100%?

For anyone still following this thread, MC798322 shows that this is still being released to General Availability (GA) and expected to be completed by the end of October. We have some in our environment who have this functionality and some who do not yet. They all should soon.

Do you know if this bug was ever fixed? I am having the same issues 10 months later (in New Outlook desktop app, version 1.2024.829.100)

I'm still having this issue so am reverting back to the Classic version of Outlook. Frustratingly, it doesn't appear to be functionality that is in the New Outlook.
