I have a new computer with Office 2003 installed. Outlook was running fine but now I am receiving the error "the messaging interface has returned an unknown error. If the problem persists, restart Outlook". I am getting this error when I try to create a new email message. I have uninstalled and reinstalled Office with no change. We are running our emails on an Exchange server.
Unlike a lot of the other issues posted regarding this same type of error, I can move emails between folders and delete items. The only thing that I can find affected is creating a new email.
Help is greatly appreciated.
