Hi @ScottDarth
Welcome to our forum!
To delete a calendar in New Outlook, please follow these steps:
In Calendar, in the pane on the left, point at the name of the calendar you want to remove.
Also, for the case of New Outlook freezing, you may try to repair your outlook app and check if there is a difference. Go to Start>>Settings>>Apps>>Apps&features>>Outlook (new)>>Reset/Repair.
