Just this morning, when any user trys to send an email through outlook, outlook creates a second folder called "outbox1" and the messages sit in there.

Recreating the connection to the server results in the deletion of the outbox1 folder but messages now sit in the outbox and do not send. Receiving is fine. Sending from web client fine. Just backing up and trying upgrade to 4.5.7 to see if helps. any thoughts soon would be greatly appreciated.

submitted a support request but wish to see if anyone else had this issue.
