I am using outlook 2003 in a domain/exchange environment

I have my outlook configured correctly to access my exchange mailbox with no problems. I then added an additional mailbox (which i have the proper access too) and it shows up in my mail folders and i can access it correctly and see all the emails in all the folders in that additional mailbox EXCEPT under the inbox?? When i look at any emails in the inbox it gives me the following error in the reading pane:
"This itemm cannot be displayed in the Regaind Pane. Open the item to read its contents"

Its wierd casue i can read any other emails in this mailbox under any other folder and this is only happening in the inbox. For example if i move this inbox email to another folder under that mailbox it shows fine in the reading/preview pane....

Here is what i have tired so far..
recreating my outlook profile
recreating my local computer profile
re-installing outlook 2003

Whats even more odd is that i use two computers, and on the one computer it works fine.. i have looked over all settings for the computer and in outlook and i am not able to find what is different and why its not working on this other computer

any ideas?

Thanks
