Warning! SP1 upgrades Entourage Identity

After applying SP1, when you open Entourage, your database will be
upgraded.
This is a lengthy process. Once Entourage has upgraded your database, you
will be unable to open it in a previous Entourage 2008 version. You will
get
an error "This Identity Cannot Be Opened With This Version of Entourage",
if
you ever use "Remove Office" and re-install without updating. For this
reason, I suggest that you make a backup copy of your Identity in case for
any reason you install SP1 and want to revert back to 12.0.1.

This was covered in the Entourage Help Blog entry:

Office 2008 SP1 Update (12.1.0) released
