How to disable Read-only

[bigmc6000]

I've got an excel sheet from a guy at work who decided to lock the entire document down so I can't do anything with it. Virtually all the ribbon options are greyed out, there isn't anything locking it in the code, I've tried checking the save as "read-only" option and it's not there. Any ideas on how I can actually save this is editable? I've looked in windows explorer and it's not read-only in there either. I tried save-as and even tried making it an XLS instead of an XLSM and it still won't let me edit it - really frustrating...

Thanks!

I found it - he had marked it as final in the "Prepare" option. Very sneeky...
