Could not move calendars to iCloud because errors occurred
I have been going through password **** because misunderstanding what password was needed when I need to verify my password for email. I ended up have to change my Apple ID password because I thought it was asking for my email password. My Apple ID and email are the same. The confusion lasted a while until I realized maybe it was asking for Apple ID. So I ended up changing my Apple ID password which went fine, however I have been in maze of requests from mail to connect with iCloud which I got to work, but I'm stuck on allowing my calendars to upload to the iCloud. So I keep getting the message in the header above.
The computer is a late 2016 MacBook Pro running MacOS Mojave 10.14.1.
