Outlook 2003 WinXP

Help, I have 2 important emails in my out box and Outlook will not send
them. They did not go automatically as usual nor when I click Tools/Send
All (I have an always on high speed cable connection). Everything else
works normally, Outlook even receives email fine. I have a good connection,
Firefox and Outlook Express (for newsgroups) are all working fine. I have
made no changes regarding the system or adding/removing programs. I need to
get these two messages on their way ASAP.

Help Please.

Thanks in advance... Bob
