Thanks for replying, I am a home single user, I wish to delete the school calenders ( that i subscribed to) only. I have other calenders in that calendar folder that I wish to keep. I right click on the calendar is wish to delete and click delete and it gives me the error message from above. I get the error message every time I try. I am the administrator, and the program memory is not full. Any other advice would be appreciated.
