Primary and Secondary iCloud ids AND resulting multiple calendars / contacts
I have tried to find this question answered but haven't been able to find an answer to this point... Thanks in advance for your insights. Here is ths situation:
I am registered with iCloud using my longstanding primary appled id based upon my hotmail address. When signing my devices and Mac up to iCloud I responded to the prompt and created a me.com email address so I could begin using iCloud mail on my devices and Mac. I am successfully syncing my iCLoud mail (me.com), notes, contacts, reminders, calendar and photostream across my devices and Mac.
In my Mac iCLoud preferences tab I have all the approproiate serivices selected (notes, calendar etc).
In the Mail / Contacts / Calendars preferences tab on the Mac I notice though that I have two iCLoud accounts showing, the primary one (linked to my hotmail account) with all services ticked and the secondary one (attributed to my new me.com account). The second iCLoud account has mail / contacts / calendar ticked also. and a note saying that only the primary one can support some services (eg photostream) - makes sense.
Here is my question and source of confusion:
1) I therefore have my primary and secondary iCloud account mail / contacts / calendars showing as separate iCloud accounts preferences though I don't see anything duplicated. Is the secondary iCloud mail / calendar / contacts just another 'reference' to the primary one or is there a second calendar and contact list underlying it?
2) Can I and should I delete the secondary iCloud contacts / calendars account from system preferences using the minus sign? If I do this will I still get the me.com mail through the primary iCloud account?
Hope this makes sense.
thanks
