My Outlook Calendar wont allow me to add or make changes

This is the New Outlook. I rarely use the old one because it had so many problems

that last message was aimed at Greg Doyon Switching back to the old calendar [before it closes at the end of this year] and then switching back to Oulook2 in my case sorted the problem Dont understand why but it worked

Understand fully but they are going to shut it down at the end of this year so be brave switch back to outlook if it doesnt work just switch back again

After lots of research I’ve found a great mail handling system and calendar mgt tool. Competitor to outlook. Superb, it just works and is easy to get my head around without the benefit of an IT department to call on. It’s called Thunderbird. Really good. Only problem - no iOS mobile option. No app. If they crack that one, they will have Outlook beaten. Here’s hoping!

Thank you. I uninstalled the new Outlook, and my old calendar

came back. This has been such a hassle that I don't have the

fortitude to reinstall new Outlook. Will let matters lie for now.
