i am trying to create a document in Excel 2010. I am trying to protect the sheet without success. Both the protect the sheet and the protect the workbook are greyed out. If I go back to the File tab, under permissions, it is set up for anyone to be able to make changes, but the only option that is NOT greyed out, is the option to restrict permission by people. I dont believe i have this password protected anyplace. I am the only one that has access to this file, not networked etc. I have all administrative rights, etc. this is starting to drive me up a wall.... any thoughts?
