I have subscribed to my sons school calendar for each subject. They do not give enough information as do the schools teacher pages. I wish to delete the subscribed calendars. I can't, it give me the below error.

" Cannot delete this folder. Right-click the folder, and then click properties to check your permissions for the folder. See the folder owner or your administrator to change your permissions. The folder is full. "

I am a home user with two computers. I am the administrator and it is set so. I check the properties and the permissions section is grayed out. I have recently archived, and I would guess that the folders are not as full as they were. ( ? )

How can I delete these calendars? Thanks for your help in advance.
