"If you see this message at the bottom of the application window when you try
to modify a document: "This modification is not allowed because the document
is locked," the document is protected with an editing restriction of No
changes (Read only) or Comments in Word 2003 (or a restriction of Comments in
Word 2002 and Word 2000). The document author used the Protect Document
features to restrict editing. Menu commands also might be unavailable,
depending on the permissions that were granted to you by the document author.
Note When you open a document that is protected by Information Rights
Management (IRM) in Word 2003, you might have permission to view the document
but not to change it. When you open the document, the Shared Workspace task
pane opens by default on the right side of the application window. In the task
pane, click View My Permissions to see your permissions."
