Why are my revisions visible when I send out a Word document?

I am reformatting a document that was sent to me by someone who had been using track changes. I told her to accept all changes and make sure she turned off the track changes feature before she saved the document. She assured me that she did that.

When I opened the document the tracked changes were turned off. I also removed the option under Tools and Options -- Editing tab "Keep track of formatting," yet it is still tracking some of the changes. It is mainly tracking formatting each time I use the Draw Table feature to split cells in a table.

What is wrong? Please help.

The article is very useful but on one of my documents I do not have the option to accept all changes this function is greyed out.

I also do not have the option to accept changes as the function is greyed out. Any help with this would be appreciated. Thanks

THANKS that is exactly what I needed to know.
I hate that revision thing. JUst want it to go away forever.

Regarding the question from several commentors about why the "accept changes" function is greyed out, the document may be protected. Go to Tools, Options and the Security tab to see if there is an option to "unprotect" the document. Click on it. If a password box pops up, the author has sent you a "protected" document. Changes you make in a "protected" document most likely will be revealed to the author when you return it to him/her, including the date and time you made each change. If you are concerned about protecting this sensitive information in your revised document, copy and paste the entire document sent to you into a new document. Be sure that tracked changes is turned off in the new document before pasting what you copied into it. If you then want to turn on track changes in your new document, you can turn it on and the functions that were greyed out in the original document should now be available. If you do turn tracked changes on in your new document, consider whether you want the person to whom you are sending the revised document to see the date and time of your changes. If not, go to Tools, Options and the View tab and be sure that "Screen Tips" is unchecked so that the date and time information bubbles are not automatically displayed as your mouse rolls over changed text. (This still may not protect all sensitive information.) Heed Leo's caution about turning off the auto fast save option in the Tools-Options-Save tab. Before you send the document back, consider whether you want to protect it, or scrub it depending on whether you have a scrubber tool and the scrubber's options and capabilities.

Excellent thank you, took you 2 minutes in your explanation to help something I've struggled with for months

Leo directed me here after I asked a very similar question, and I found his description very useful :)
I'd managed to accidentally turn on the tracker, not noticed, and was then stuck with the red 'modifications' every time I opened the document.
I just needed to accept all the changes, and everything went back to normal again. As a bonus, it halved the size of what was a considerably large document to begin with.
