Some people that I try and help have "Outlook" problems to the extent that when they send a file with large attachments, you might get the same email 50 times...as it seems to be caught in some sort of electronic loop. Once in this loop they can't shut it off and the mail doesn't even appear to be sent so they compound the problem by resending it again...so another 50 fly out.
That seems to piss people off.
And they wonder why.
