This is very unusual behavior. You mentioned a second computer running Outlook, configured to the same profile.

- What version is that outlook client?
- (On the computer with the issue) have you added the inbox to favorites to see if this works around the unusual error?
- Do you have Office 2003 or outlook 2003 to perform a full uninstall /install of the program?
- Does your excahnge hosted provider offer an Outlook upgrade?
_ have you attempted to use the Outlook switches " /resetfolders or /resetfoldernames?

Here is a link to better understand Outlook switches;

With outlook 2003 nearing extinction, if the above methods do not resolve this issue, it might be time to upgrade to 2007 or 2010 versions.

Hope this information was found helpful.
