I received a workbook. On one of the sheets there are some cells which cannot be accessed. I just cannot use mouse or arrow keys on the keyboard to get into these cells. When I click on one of these cells, nothing happens. What I find intriguing is that the sheet or the workbook are not protected and particular cells are not locked. If I enter the cell address in the Namebox, that cell will be accessible. If I open this workbook with security level high then all cells are accessible. This makes me believe that the cell protection is through VBA code but since the VBA code is password protected, I cannot access it. Also I am not authorized to share the file with anyone. Does anyone has any idea how this could be done. This is my first post here, so, please bear with me!
