automatically logon to exchange server in another domain

Goodmorning,

Another question : I have 3 domains

lets say it is michel.global this is where my xp client logons to.
Besides that I have a new domain called michel.grp. This is server 2008 with full AD. Besides that I have michelres.grp that hosts exchange 2007 server.
There is a one way trust between michelres.grp to michel.grp and there is a two-way trust between michel.grp and michel.global

I installed outlook 2007 on the xp-client. I can access the exchange server at michelres.global, but everytime I have to give in my password. Of course I can use the “remember my password” option, but due to security I am not allowed to do this. So my username on the michel.global is different than my username on the michel.grp and michelres.grp

Is there a way to have a SSO at the XP client to the exchange server in michel.global. Those are seperate domains. I’m not allowed to set it up on another way.
I want to logon to the exchange server without typing my username and password. Is this possible?

I don’t think it is (maybe i am wrong .. i hope)
