Protect document with password

I must lock this patent memorandum before sending it to outside counsel. Protect the document with a password so recipients can view but not edit. Apply a strong password I will provide, restrict formatting and editing to disallow changes, and confirm you can open the file and that tracked changes cannot be accepted without the password. Save the protected file as Memo_Patent_Protected.docx and tell me if any embedded objects or macros prevent protection from applying.

Before I send the draft to the client, make the protection clear and reviewable. Summarize what the protection does and does not do up front: whether it blocks editing, copying, printing, or track changes, and list any elements that bypass protection like embedded spreadsheets or linked files. If protection might break our review workflow, propose a lightweight alternative such as a read-only PDF export and explain the trade-offs in one paragraph.

I applied a password to restrict editing on the confidentiality memo, but an external reviewer still edited and saved changes. I thought protection would prevent edits. I don't know whether they opened a copy, removed protection locally, or used a PDF conversion. I must keep the workflow moving but protect confidentiality. What are the likely ways my protection failed, how should I verify the file's protection status, and what's the best immediate action to ensure the document cannot be altered by recipients tonight?

We keep sending drafts and then have to re-issue protected versions because someone forwarded an editable file. This creates version chaos and security risk. Where are we losing control in our delivery steps, what habit must change in the team that prepares outbound documents, and what single operational rule or tool practice would stop recipients getting editable copies unintentionally?
