I've discovered I have 2 calendars. One resides on our server and I
am able to use reminders on that one. The other resides in my
personal folders and is the one with the problem as described
previously. I'm wondering why they behave differently.

You can have only one set of default folders and reminders work only in the
default folders (i.e., where your delivery location is). You can purchase
third-party tools that will allow you to have reminders in non-default
folders as well.
