When trying to open .doc attachment from Outlook for Mac I get the following  message:- .doc uses a file type that is blocked from opening in this version. It goes on to tell me to open on the file menu but when I try that I just get the original  message again. this only started today and I have had no prevous problems like this and am baffled as to why it has just started ... any  info greatly appreciated I have tried re-setting with change all docs to MS word but it does not work
