The SP2 updated help files have finally appeared.
When Service Pack 2 was released there were also new help files for all parts of Office 2007 with the notable exception of Outlook 2007. At the time we called the Outlook 2007 help files ‘missing in action‘.
In early June the Outlook help files (user and developer) finally appeared here.
No reason or apology has been given for the five week delay.
