Conflict Message Error when trying to Open a Meeting Invite

I am facing the same issue from last month and getting reminder for a meeting which happened almost a month ago. Conflict error is very annoying and every time when you click on a mail related to the invite like accept or denied from someone, it says, this meeting is not available or deleted in your calendar. Please resolve this quickly.

Can you confirm if the fix is applied automatically or is there something we need to do on our end?

We have users still reporting the issue so please confirm without copying your previous message. Thank you.

The fix is now live worldwide. Outlook Dev says it went live last evening at 10:00 PM PST 7/11/24.

New meetings that you create now should not have conflicts. If you find otherwise, please let me know.

If you had meetings with conflicts those will not be automatically fixed. To clear those you can use Workaround 2 in the Known Issue article, Outlook shows conflict errors when updating or cancelling meetings - Microsoft Support. One thing to note is after you Clear Offline Items you can click Send/Receive to sync down a new copy of the calendar items from the service. Outlook will pull them down normally too but that can be done to expedite it.

If you have duplicate meetings caused by the conflicts use Workaround 3 in the Known Issue. Make sure to edit the calcheck.cfg file and set all rules to False except for DupGlobalObjectIDs. I will see if I can add this to the Known Issue, but you can use this calcheck.cfg that is ready to use CalCheckConfigFile. Replace the one that came in the folder with Calcheck with this one.

Do we need to do anyting on our end? or does the fix get automatically applied
