Edits to Calendar Events can't be Saved

About a month ago, I started having an issue with saving edited calendar events on a shared calendar that I manage. When I go into an existing Event and edit information such as the date, time, title, or other information and hit "SEND", I get a pop-up saying, "Something went wrong", that "We couldn't save your calendar event. Waiting a bit might help. Keep your calendar event open to try again later." (image of this pop-up is attached).

I have tried to "resume editing", and of course, have waited with the event open, but it still won't save. It seems like this is an issue many others are experiencing as well. Solutions I have seen on other threads include turning off weather displays on the calendar, clearing your cache, and using the app instead of a browser. I have tried all of these things, but nothing has solved this problem. I manage many regular calendar events, and it is a huge hassle to have to delete an original event and replicate it over again from scratch when it only needs a small update, and everyone invited to the event sees the cancellations and re-invitations and becomes confused.

Are there any other solutions that might help? Any updates soon? Thank you.

I also have the same issue.

This did not work for me at all.

WIth the new outlook i am struggling to find the areas to even try to do what you say here.

Is there an easier fix?

this is an absolute nightmare

I'm in Australia. I found another post here where someone from Microsoft replied to someone regarding the same frustration. I'll try what they said and then get back to you.

Um, they're not listening.

This started for me about 4 days ago, self-cured after about 36 hours, was good for about 2 days, and is returned.

Where are you, Satya? We need to talk.

I Just had an update and I hoped..... but no it made no difference - FIX THIS
