I just upgraded from IS 2009 to 2010. Prior to upgrading the "spam" task bar wouldn't load in Windows Mail, but it would in Outlook 2007. Now I have exactly the opposite - it works fine in Windows Mail, but when first starting Outlook after the upgrade I got an error message saying there was a conflict and I couldn't run Outlook with the Spam bar.
I've searched this forum and couldn't find this problem mentioned. (My apologies if I didn't search well enough.)
thanks.
