Delete Sheet is greyed out

[Cape_Town_Bob]

Hi

I am tidying up some old files and want to remove sheets.  When I tried the "delete sheet" command is greyed out.  Is there some sort of protection on?

Check the Review tab, I bet Workbook Protection is on.

In my case, it was caused by 'old style sharing' being enabled. Simple to disable in the Review tab as well.
