Can't Edit Shared Calendar from Outlook.com after Upgrading to iOS 17
Prior to upgrading my iPhone to iOS 17, I was able to add events to a shared calendar (outlook email account) with my wife without issue. After upgrading to iOS 17, all events on my calendar on my iPhone are un-editable. The only thing I can do is indicate accept, maybe, or decline. The invitation shows as being sent from my wife and me as the invitee, even though I can create the event on my iPhone, iPad, or Laptop. I have logged into my online account on my laptop and am able to edit/modify the events just fine, but don't see the similar experience as the event coming from a "third party" that I'd need to accept. My iPad is not on iOS 17 and I can create/modify events without issue. I am logged in with the same Apple ID and Outlook account on all devices. I have also made sure my contact card on my iPhone has the address I use for my email and we've verified I have "edit" permissions on this calendar. I've tried removing the account, rebooting my phone, re-adding, etc. multiple times and nothing works. Apple indicated this is not their issue, but a Microsoft issue. What can I do to resolve this issue?
I can confirm that with a shared Outlook calendar, if my wife adds an event to that calendar from her iPhone (iOS 17.1) it immediately appears as if I invited her to the event, and she only has the options to accept/maybe/decline the event. She cannot remove or edit it. Actually, it auto accepts the event.
