Peter ,
Kindly note that
McSaCore.exe is a McAfee service.... I can see that in my machine too( Process ID 1812 and it has a Valid McAfee Inc signature too....
location is
"C:\Program Files\McAfee\SiteAdvisor\McSACore.exe"
Version:2.08.0000.0232
My outlook is working fine..

but if the disabling of that service is resolving that issue it could be a conflict please let us know if there is any other security application on the computer (other than McAfee)

that service interacts with OLE32..hmmm.... see if this file helps you in the mean time
