office 2010, save and send giving error in all MS office apps

We just installed MS Office 2010 on win XP Pro machine. When we go into any office application and try to send an attachment from within the application(file, save and send, send as attachment) we get an error. “excel/word/powerpoint/ect encounted a problem and needs to close. Sorry for the inconvenience. The information you were working on may be lost. MS excel can try to recover it for you”. We are using outlook 2010 and exchange. Outlook is set as the default mail client. Any thoughts?
