Contact list and attachment problems.....

I have a 2 major problem with Microsoft Office Outlook 2007 with Busines
Contact Manager.

1) When I sent email in outlook from the selecting recipients from the
contacts, the email doesn't get sent, it seats in the Outbox. However, if I
type just the email address and it works fine. Any way to fix this?

2) When I save the attachment from any emails, I get 2 folders created
at the same time in the folder I save the attachment. The 2 folder is called
"outlook calendar" and "outlook contact" and they are empty.Any way to fix
this?
