If you want to protect some parts of a Word document from unauthorized editing, you really can not avoid the use of controls. These can then later be treated as form areas, and be protected separately.

So suppose that you have created a letter with form controls, and want to explicitly protect certain areas here, then go to the “Design Mode” in the Word menu via the tab “Developer Tools” and select the context menu (right mouse button) Properties of the element concerned. In this way, you can protect each individual element separately before processing.

You can certainly see that while this method is quite labor intensive, on the other hand it offers the widest variety of restrictions on third-party access.

It is a bit easier in Word to go to the tab “Review” – “Restrict Editing”, and there, under the possibilities given by Word to restrict editing. Here you can protect the document so that either only edits of comments, the completion of form fields is allowed, or just no changes may be made.

If you want to completely protect your Word document from unauthorized access, the simplest method is to use the Word menu “File” and select the “Protect Document” section. Here you can provide the entire Word document, for example, with a password protection, so that the file without a password can not be opened at all.

However, you should remember the password of course well, otherwise it will be difficult for you as a creator to get back to the document again.

As you have seen, depending on how extensive and dedicated you want to protect your Word document, it is more or less costly to do it. Of course, it would be desirable that Microsoft offers more options here in the future, just as it is possible, for example, as in Excel, to release each cell individually for itself or even to block it.

By the way, the possibilities of protecting your document do not offer 100% security. Because the password protection which can be used to open the Word document can be leveraged with appropriate tools on the Internet in part. But it’s still better than not doing anything to guard against unauthorized access.
