Microsoft has posted a fresh update for Office 2008, v12.2.7. The patch is a relatively minor one, correcting just three issues. Some crashes triggered when starting Excel have been eliminated, and Entourage should no longer create duplicates in an Exchange 2007 mailbox. Entourage has also been scrubbed to solve problems with Exchange authentication using the Kerberos protocol; the program previously had trouble detecting expired credentials and renewing tickets.
