Using Classic Outlook on Windows for personal email, calendar, and contact management
Totally completely agree with you. I spoke to MS support about this yesterday and they acknowledged the when switching to the new Outlook, if you use a MS Business Basic account it won't work. I weas told this "may" change as the app is still in preview mode. I was however told that if you activate the new Outlook with Standard or above, you can then add Business Basic accounts. So I did that - activated the new Outlook using an Enterprise licence I have. However when I then tried to activate several Business Basic licences I was met with the same error every time. So no choice but to revert back to the old Outlook for now until MS sort this ridiculous situation out. And agree - the fact that you can add a 3rd party account (e.g. Gmail) makes this even more farcical.
