Sadly, there is nothing in the terminal output or in journalctl. It seems as though the username/password dialog box takes the input, but then the "Add" button fails to become active. Reproducible every time.
** Description changed: Upon attempting to add a calendar from outlook.com, I was greeted with a username/password dialog box. So, I entered my username (an email address in this case) and an app password I generated since I have two- factor authentication. The dialog box would go away, but the calendar would not be added. + + It seems as though the username/password dialog box takes the input, but + then the "Add" button fails to become active. Reproducible every time. The only workaround was to add the calendar using Evolution, which properly accepted the username/app-password and added the calendar. Unfortunately, at that point, I discovered bug #185227.
