Hi Keerthi,
this allows me to untick both of the options, I just need to prevent selection on protected cells, not on unprotected ones too.
This is the desired configuration:

But with your help I managed to find the solution
sht.Protect(passwd, ExcelSheetProtection.Objects And ExcelSheetProtection.Scenarios And Not ExcelSheetProtection.LockedCells Or ExcelSheetProtection.UnLockedCells)
Thank you
Best regards
Adrian
