There is no problem with your Outlook settings – the issue is with the outside hosting system you referred to as “”www.1and1.com””.
The E-Mails from your boss are not reaching your inbox at the hosting site. Outlook will not down load any messages not in the Inbox Folder. Contact your E-Mail hosting company technical support and they will advise you how to modify the spam settings on THEIR system to prevent e-mail from your boss getting sent to your SPAM folder.
