Had a suspicious email, spam from Amazon.com with zip attachment. I did not open, but forgot and try to try drag email to spam folder instead of deleting. I did a full system scan. Nothing was found, but I now can not access email on Outlook 2010. Error codes are 0x800CCC80 & 0x80042108. From what I can tell, Norton 360 is blocking. I think I have version 5. Concern for pst files too.
