I changed my email for iCloud calendars won't merge
I changed my email for iCloud as well asapple id to the new email. I deleted the old apple ID accounts. Now the calendar on my mac won't sync with iCloud. The check box keeps greying out when I try to sync and the calendars don't merge. Can anyone advise please?
Thank
