Can't insert new sheet into unprotected workbook

[reganshaw]

I have a workbook that was shared and sent to me to update.
I have unshared it and it is not protected however it will not allow me to Insert, Delete, Rename, Move or Copy, Hide or Unhide any sheets (options grayed out).

Any ideas why I cannot add a worksheet?

Is the Project password protected?

Yes, just found it - the workbook is set to Restricted Editing (Protect Structure and Windows), and requires a password. The individual who set up the workbook is no longer with the company.

I have found code to unprotect worksheets in the forum here but cannot find anything to unprotect workbooks. Is it possible?
