I have a group of 36 emails addresses and I have been using this for two years with Windows Live Mail 11.

Now on a new PC with Windows Live Mail 12 I either

A)  get a message

----------

 The error message box with the heading Windows Live Mail states

The message could not be snet

Type an email address for one or more recipients in the To CC or Bcc box

--------------

or

B)  the email message is sent only to me  (a member of the group)

This problem was discussed in Oct 2012 in this forum but there is no Answer there.

Many thanks
