Have you recently changed ISPs? If so, change your settings.
Also check the SSL box in Outlook. Go to Outlook and tools menu, use the properties tab of your email account and under advanced settings, check the "the server requires a secure connection (SSL) box.

What size is the attatchment?

What size is the arratchment?

That's a thought if they are over 64kb (I think) the settings need to be changed - I may be wrong though. :)
