Restrict permission to content in a file
To restrict permission to content in a file, you have to have Microsoft Office for Mac Standard 2011.
Information Rights Management (IRM) allows authors to restrict permission for documents, workbooks, and presentations on a per-person or per-group basis. For example, Ranjit, the author, can give Helena permission to read a document but not change it. Ranjit can also give Bobby permission to change the document and allow him to save the document. Authors always have Full Control permission.
IRM provides three permission levels.
Read, edit, copy, save changes
Read, edit, copy, save changes, print, set expiration dates for content, grant permissions to users, access content programmatically
Do any of the following:
Set permission levels manually
Use a template to restrict permission
Change or remove permission levels that you have set
Set an expiration date for a restricted file
Allow people with Change or Read permission to print content
Allow people with Read permission to copy content
Allow scripts to run in a restricted file
Require a connection to verify permissions
