I cannot open attachments sent via my yahoo email account!!! Please help.?

Try this troubleshooting: http://help.yahoo.com/kb/index?page=content&id=SLN3222&locale=en_US&y=PROD_MAIL_ML If that helps, fine. If not: create an account with a different provider, forward the original mail incl. attachment/s to your new account, and open/download it from there. During the past 3 weeks more users than usual have reported the same problem like you, we all hoped that after the maintenance those problems would be over, but apparently they are not. And Yahoo is trying to downplay the problem by having a staff member answer related questions with a canned response just a few hrs before the answering period is over. Occasionally said staff member even claims there is no workaround although my suggested workaround has been helping quite a few users in the past. Note: I certainly appreciate all the help we can get from Yahoo staff, but I regard it as highly counter-productive, when a staff member tries to downplay a problem by claiming that it only affects a very small number of their customers. We don't know whether it only affects a small number of their customers, but something is definitely wrong if users keep reporting the same problem over and over...:-(
