I've recently upgraded Outlook Express to version 6 but now find I can't open some attachments. OE6 tells me it has "removed access to the following unsafe attachments." There doesn't appear to be any pattern as to which ones I can & which I can't open. I thought it might be that certain file types are barred or attachments that have been downloaded since the upgrade but this is not the case. I'm running McAfee Security Center on a 98SE PC. Any ideas how I can get OE6 to open them?
