  • Error code points to that the connection is dropped.

    Am not getting what you mean by remove/delete from send action?

    also  i dont think yahoo is going to accept a 57mb attachment.

    Window Live mail do not accept such huge message size, thats why the program showing the error.

    Even you send out the mail successfully from Window live, reject message from yahoo still can be expected.

    Please refer this for attachement limit.

    To share your video, go for MSN SKYDRIVE and send your friend a link to pickup.

  • Split up your attachment to 10-15mb each then I think you will be fine
