Must have deleted it by mistake when I was setting up. But the icon is gone, or at least I cannot view the calendar anymore. Any help please?
Deletion of calendar would have a confirmation message. Do you remember you had such confirmation message? Because if you really delete it by mistake, that means you actually delete it. There’s no ‘Trash’ folder for calendar for you to revert this action back.
I found it, was very lucky. I didn’t know it was hidden in my Mail Icon
