Hi,

Is there any functionality in Excel which would automatically lock a
workbook, preventing unauthorised entries being made after a specified
time, and unlocking itself after another pre-determined time.

Authorised entries should be permitted under password control whilst
locked.

I suspect there's no standard functionality, but maybe someone can
comment. Alternatively are there any third party tools round which
might achieve this requirement. I've googled around but not spotted
any.

Usual TIA
