Maybe instead of putting it on your local disk only, you could put the
file on a network drive after enabling workbook protection with
password. That way, everyone will be able to access and read it, but
only you and the other guy will have the passwords and hence the
capability to actually edit.

I have done this for a number of my work files, and it has worked great
for me! Hope it does for u too!

Hi Nancy,

To stop others modifying you need some kind of password protection.

Go to Save as, on the screen in the top right hand corner click on
tools - this will give you some options and only those with a password
can modify.
