I have been receiving the error codes every time I run the following Windows updates:- KB921896 - MS SQL Server 2005 Express Edition Service Pack 2 KB946140 - Update for Business Contact Manager for Outlook 2007 KB948109 - Security Update for MS SQL Server 2005 Express Edition Service Pack 2 KB951944 - MS Office 2007 Security Update KB957829 - Outlook 2007 Junk Email filter I am running Vista Home Premium and Office Professional 2007. In addition, I installed MS SQL Server 2008 Express Edition. I uninstalled it on discovering that it was incompatible with Outlook 2007's Business Contact Manager (isn't this ridiculous?) and reinstalled MS SQL Server 2005 Express Edition. Please advise what I need to do as some operations in Outlook 2007 generate Business Contact Manager error messages about being unable to connect to the database - I assume that all these update error messages are connected.
