Question : Outlook 2007 receives HTML mails in Plain Text  ( from one domain )

Hi 2 all experts,

I have a problem that is getting annoing , it`s like this ..
In our company we have 2 separate domains , each one with his own mail server ( one is Exc ishange 2010 , and one is a linux mail server ). All the clients have Outlook 2007 installed ( with win xp or win7 ).
We will call the Exchange Server - A , and the Linux Mail Server - B.

The problem appears when sending a mail from a adress from server A to a adress on server B. He receives the HTML e-mail in plain text format.

The odd thing is that on a few computers it works just fine , they receive the e-mail in html format.

Any ideas ?

Thanks in advance.
