I like the Entourage calendar. Very nice.
How can I find the file so I can back it up? I lost a lot of data on a Now-Up-To--Date file I failed to back up.

From the ReadMe file that came with Entourage v.X (ReadMe folder of Microsoft Office X app folder):
6Maintaining Your EntourageX Data
6.1Location of Your Entourage Data
Entourage stores data such as preferences, rules, schedules, signatures, messages, contacts, and all other Entourage items in a database on your computer. The first time you start Entourage, a new folder, called Microsoft User Data, is created in the Documents folder. Within the Microsoft User Data folder, Entourage creates a folder called OfficeX Identities. This folder contains the Main Identity folder, which stores the data for the first identity. Each time you create a new identity, Entourage adds a folder for it to the OfficeX Identities folder.
You can move your Microsoft User Data folder to a different location, including an AppleShare server. To do so, place an alias to the Microsoft User Data folder in either of two places: the Documents folder in your Home folder, or the Preferences folder in the System Folder. We do not recommend that you store the data folder in the same folder as the Entourage program. Some users who have done this have accidentally deleted their data when they deleted the program folder.
6.2Backing Up Your Entourage Data
We highly recommend that you make regular backup copies of your data so you can restore it in the unlikely event that your hard disk is damaged or your data becomes unreadable. To make a backup copy of your data, drag the identity folder you wish to back up to another volume, such as a different local or network hard drive or a high-capacity storage disk. To restore the data for an identity, drag the backup copy of the identity folder to the OfficeX Identities folder.

Much thanks. (Although I am humbled that I didn't manage to find it in the readme.
In any case, much thanks.
