Recently I purchased machines with 64bit windows 7 operating system and office professional 2010. Outlook 2010 norton antispam is non fuctional on all of these machines. I read on the forum that client integration is not supported for 64bit windows 7. Is this true and when will this issue be addressed? Is there a patch to download to correct the issue? A non functional spam filtering antivirus program is not what we wanted to purchase. Please advise.
