Upgrade problem from Outlook Express to Outlook

[a]

Was and still am able to send mail from Outlook Express, but not with Outlook
2003. Ran the upgrade procedure to import settings and contacts from Express.

Deleted those settings in Outlook and re-imput them. Also, made a new
profile. Nothing helped in Outlook, though the mail continues to work in
Outlook Express.

Anyone have any ideas what I can do to get Outlook 2003 working properly?

Thanks,

Paul
