¿? MSG sits in outbox with attachment.when you send to a group

[quell]

OK here is a good one. This problem just started. I have exchange 5.5 on w2k server with all the hotfixs etc.. for both exchange and w2k. When a user sends an email attachment (*.xls) to a group of people (distribution box) the recipients will not receive the msg and it sits in the senders outbound box. This msg is 47k and this attachment is not restricted and there is no restrictions on size. However if you specify the recipient it works fine, even if you specify more then one recipient. I have tried to restart the server, looked through the event logs with no luck. Please help. Any ideas are welcome
Thank you

Guess there seems to be a problem with nortons AV for exchange. FYI: version 2.18 built 80
Thanx
