MicrosoftHi euburrag !
Calendar invite changes made should automatically update the invite for all those who have accepted. There should be an additional push for them to re-accept, nor for them to be notified of changes made to the body of the event invite.
Also for Groups calendars (Calendars from a Teams channel/group) should be viewable on the groups sharepoint site. There is no way to have it show on Sharepoint without creating a PowerAutomate flow. This didn't used to be the case and it is causing a lot of trouble at my company. One used to be able to have a calendar on Sharepoint that had an email address. One would then only need to add that email address to an existing calendar invite which would result in the event populating on the Sharepoint calendar. That is no longer possible with O365. I hope they reinstate this capability.
THanks!
