The Editing restrictions section allows you to do just that. You have four options for restricting editing – Read only, Tracked Changes, Comments and Filling in Forms.
The Comments restriction only allows you to enter in comments in the document. No other changes can be made.
The Tracked Changes option will allow you to edit any of the document, but will force Tracked Changes so any changes made can later be reviewed.
The option we’re interested in is the last option – Filling in Forms. This will only allow end users to edit text that are in the specific controls we set up earlier.
The Read-only option does give you the option where you exclude specific people. By default, the Read-only option will apply to all users, but you can easily add specific users in if you are on a corporate domain.
Once you are happy with the restriction you wish to enable, click the Start Enforcing Protection button (Figure 5). You will then be presented with the option to password protect the enforcement. If you don’t want a password set, just leave the password fields blank.
