With the Highly Confidential label, you need to enter the users' accounts (usually their email addresses, but not email aliases) with which your users use to login to their Microsoft Office applications.  They will also need to have a valid Microsoft Office license when the open the protected document.

Notes: In HKUST, all users are using their email accounts (not email aliases) to login to Microsoft Office. However, some external users are not using their email addresses to login to Microsoft Office. You will need to ask your users which Microsoft accounts they are using to login to Microsoft Office before entering their accounts when protecting documents with AIP.
