You can back up everything by copying this folder to another drive:
/Users/<Your User>/Documents/Microsoft User Data/
This includes other settings including Word's Normal Template
<
http://www.word.mvps.org/Mac/MacWordNormal.html>, Printing Forms, Messenger
Data, and some other Entourage data like scripts and sound sets. If you
only need to back up your Entourage identity, which includes virtually
everything in Entourage except scripts and sound sets, you can just back up
the "Office 2004 Identities" folder within the above-referenced folder.
