I've been racking my brain trying to figure out what could possibly be
preventing me from applying permissions to my excel spreadsheets.
Everytime I try, the following message appears:

This service is temporarily unavailable. Microsoft Internet Explorer
may be set to Work Offline. In Internet Explorer, verify that Work
Offline on the File menu is not selected, and then try again.


I've already installed the IRM Add-On for IE, but still to no avail.
Does anyone know what the problem is? I have an internet connection
and I'm not set to work offline.
