I have about a dozen accounts in Outlook 2011.  when I select a new message it always opens it in the default account, with the signature attached to it.  if I now change accounts the signature stays and I need t change it by deleting it and putting in the other one.  Is there a way to have this also automatically change to the signature attached to the chosen account?  Or could I choose any account of the 12 as I create a new message?
