Outlook 2003 error when clicking on reply all or forward

When I click on either of these an error message appears stating: "The message interface has returned an unknown error, if the problem persists contact your systems administrator"

I have tried creating a new profile but I get an error "The action could not be completed the connection to the Microsoft Exchange server is unavailable. Outlook must be online or connected to complete this action"

Outlook is not set to offline, and emails are being sent and received successfully.

A little background: The user is running Windows 7. I believe (not 100% sure) an Outlook 2007 trial was installed, it expired an OEM copy of Office 2003 was installed and now this is happening, I think it may have been reinstalled but I am not 100%.

Any ideas on how to get rid of the error?
