Hello- Had a frustrating day with windows mail. I've got a message stuck in
the outbox and am unable to delete it, move it or modify it in any way.
everytime I try, I get a message stating that I cannot delete or move
message. I believe that because this message is stuck in the oubox, it is
keeping me from being able to send any messages. Any help would be greatly
appreciated. Thanks.
