After trying to work with Microsoft support and Apple support, I was told that I wouldn't get my Legacy Outlook for Mac back again. So, I tried for 5 days to adjust. Yesterday I restarted my Mac and my Outlook for Mac reverted BACK TO THE LEGACY VERSION, but ALL OF MY CLIENT EMAILS ARE MISSING FROM THEIR DESIGNATED FOLDERS. WHERE DID MY EMAILS GO IN THIS UNCONSCIONABLE NEW UPDATE???

NOW I HAVE TO GO THROUGH THIS AGAIN IN OCTOBER?

    "Outlook for Mac uses separate profiles for Legacy and New versions. When switching between them—like after a restart—emails and folders may not appear if they belong to a different profile. To locate missing emails, check this folder: ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/. Also, try logging into Outlook Web to see if your emails are still on the server."
