You cannot delete the original calendar folder as it is a default folder and therefore cannot be deleted.

To the OP, if you provide your Outlook version, someone can tell you how to delete the Forms Cache that causes this problem.

After furious head scratching, Bob I asked:

| Outlook? Version? Could be a corrupted calendar. Create another

| one to Calendar.
