I created a meeting that I now wish to delete. I have a conflict error message that appears when I try to either open the meeting or delete it. The conflict error reads "One or more items in the folder you synchronized do not match. To resolve the conflicts, open the items, and then try this operation"

I am having the same issue. I get a yellow warning sign with 2 arrows and when I click on that, it gives a list with the same meeting heading, dates and times, but I cannot see the hwading of ghis doc or do anything with these entries
Same issue, Microsoft® Outlook® for Microsoft 365 MSO (Version 2302 Build 16.0.16130.20332) 64-bit
Workaround here doesn't work https://support.microsoft.com/en-us/office/outlook-shows-conflict-errors-when-updating-or-cancelling-meetings-69c26227-40ef-4377-8f12-1749fcaad2ad
Same issue - and none of the recommended fixes above are working. I am the organizer/host for several meetings with our executive leadership team - I cannot have them getting all these duplicate updates. PLEASE FIX THIS!
The Outlook Team is still investigating the issue. Its a Sev 1 incident but still slow to get to root cause. The best option for now is if you see the conflict error only make updates to that meeting from OWA or New Outlook or Teams calendar, Outlook shows conflict errors when updating or cancelling meetings - Microsoft Support.
