TRACKING CHANGES IN A DOCUMENT Word 2003, 2007

IF your data is critical and you want to ensure that you give restricted access on the document, you can either control formatting or editing changes.

To do so using Word 2007:

Open the document on which the restriction needs to be applied.
Go to the 'Review' tab.
Click the 'Protect Document' option appearing under the 'Protect' group at the end of the tab.
Select the 'Restrict Formatting and Editing' option under the 'Restrict Reviewing Options' section of the drop-down menu that appears.
Check the 'Limit formatting to a selection of styles' option appearing under the 'Formatting restrictions' section of the dialog box.
Click the 'Settings' link and check or uncheck the required option.
Click 'OK' to continue.
Next, check the 'Allow only this type of editing in the document:' option appearing under the 'Editing restrictions' section of the dialog box.
Select the 'Tracked changes' option from the drop-down list.
Click the 'Yes, Start Enforcing Protection' button to enforce restriction settings.

If you are using Word 2003, carry out the following steps:

Open the document on which a restriction needs to be applied.
Go to the 'Tools | Protect Document…' menu command.
The 'Restrict Formatting and Editing' panel appears on the right side of your Word window.
Once you see the 'Restrict Formatting and Editing' panel simply follow the steps as described above (while using Word 2007).
