When using Word track changes and comments when collaborating on Word documents. Track changes in Word to ensure error-free files.
If there are any comments or tracked changes in your document, you should remove them before sending it to anyone you're not collaborating with. Comments and tracked changes can reveal confidential information that could lead to embarrassment or make you or your company appear unprofessional—or worse.
Once you've removed all of the comments and tracked changes, it's a good idea to double-check your document using the Document Inspector. The Document Inspector can tell you if there is any hidden data in your document that you may need to remove. It looks for data in many different places—not just comments and tracked changes.
