the log is reporting problems with uploading the connections folder:
Connections - error occurred - Access denied. The file may not exist locally, may be open in another program, or there could be a local permission problem.
this shouldn't be an issue, one the connection file is set, you dont want to overwrite it any way.
Can you send a copy of your page and the universal email folder so I can examine the code to see why it is only sending to one address.
