I have two outlook.com email accounts, call them *** Email address is removed for privacy *** and *** Email address is removed for privacy ***, one for personal e-mail the other for business e-mail.   I set up *** Email address is removed for privacy *** in Outlook 2010 first and populated the Calendar, that was created, with appointments.  Later I set up the *** Email address is removed for privacy *** account and found that the calendar that was created had all the appointments copied from the X account.  This lead to duplicate Outlook reminders.  I tried to delete the appointments from the Y calendar, but then found that the X calendar appointments disappeared.

How can I have the two outlook.com accounts in Outlook with separate and independent calendars?

Assistance will be gratefully received.
