i have had to delete and re-add my account because various folders wrongly show unread emails. In doing that I am trying to change the color of my calendar, and each time I do that the calendar folder disappears. It just vanishes. The calendar shows one folder, “Conversation history,” which makes no sense in a calendar. But the calendar itself, with the appointments, etc. is simply gone.
I have deleted and readded this account 4 times to fix this,and the problem keeps happening.
