Hello.  I am using outlook 2007 on my laptop.  When I send emails from home they send just fine.  However, when I am connected to my universities internet network and try sending emails, they remain in the outbox and do not send, until I connect to any network other than my schools then the messages in the outbox are transmitted.  Why is this?  I always have to wait until I get home to send emails, it is very frustrating.  Any suggestions would be great, thank you.
