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"

This is an image of what I see when I open the appointment. I redacted some of the information for privacy. You will see this event has passed. I have this for other appointments too.
This made the appointment disappear on my calendar, but it is still listed on all of my executive's calendars.
Lisa,
All of those symptoms are related to the calendar conflict issue. If you see the Conflict Message dialog close it out. If you click Keep All it will create duplicate meetings at the same time.
After the service fix goes out later today you can do the Clear Offline Items for your calendar to remove the conflicts. Today I would make any meeting updates from OWA or New Outlook. Tomorrow do the Clear Offline Items workaround tomorrow, Outlook shows conflict errors when updating or cancelling meetings - Microsoft Support. You could do the Clear Offline Items today but if any new conflicts you will still have to do it again tomorrow.
Hello,
Something I have noticed for a short while now... Microsoft seems to have trouble with Calendar, Teams working with emails when saved as a file. i.e. I a lot of time will attach to a teams project an email for approval, etc. Or in a calendar - an original email for clarity. When I do that, I get all the errors you all have listed.
These are a few of the errors I get from my calendar meeting that had an email attached for reference.
I deleted the meeting in the Teams calendar, and it automatically deleted it in Outlook.
