New Post: Help Restoring Outlook Calendar

I used MFCMAPI to delete my outlook default calendar because I accidentally uploaded a TON of events through a CSV import. My Outlook account is for work, so the delete didn't remove the calendar from the list, which is fine, but I need to still import CSV files by the calendar no longer shows in the list when I go to import. How do I restore the default calendar in full to Outlook?>
