Greetings - I did not know where else to post this (well, actually I just thought of another site) but here goes...
My wife is using a Vaio laptop running Vista Home Premium and Outlook 2007. Frequently enough that it is irritating, but not consistently, she will send a message and it will sit in the outbox apparently unsent. Also at times, it will appear to have sent but the receipient does not receive it.
