Microsoft has released a few updates to its Office 2004 and Office 2008 suites for OS X. These updates address security bugs in the programs, and for the 2008 version they also improve application stability.
In addition to the Office updates, Microsoft released an update for Entourage 2008 Web Services Edition, which improves calendaring and diagnostic logging, as well as synchronization of notes, tasks, and categories with Exchange servers.
These updates should be available via Microsoft's auto-update utility that is included with Office, but can also be downloaded from Microsoft's Mac downloads site at the following links:
Administrators looking to install or update Entourage 2008 Web Services Edition should read through Microsoft's instructions for doing so.
As always, be sure to make a full backup of your system before updating your software, especially if you rely on Microsoft Office. Though we do not expect any issues with these updates, errors are always a possibility. Usually these will, at most, require a re-installation of Office, but having a full and restorable backup is the best practice before any installation.
