If the workbook is shared you won't be able to delete sheets. To turn
off sharing, choose ToolsShare Workbook.
On the Editing tab, remove the check mark from 'Allow changes by more
than one user at the same time'
Click OK

For some reason, I can't delete worksheets from my workbook. I am able to
insert worksheets and edit worksheets, and it doesn't appear that my
worksheet/workbook is protect. When I go to toolsprotection, the only
option I have is to protect worksheet/workbook. Any help you can offer is
much appreciated! Thanks.
