We have a user who has Outlook 2007 and it is fully updated on a Windows XP Pro machine and we have an Exchange 2003 server. Her e-mail that is sent out is having intermittent delays. People are getting the e-mail she sent out hours after. There are no errors on the server or on her machine. When we check the Exchange queue, nothing shows hanging up. It is not a particular e-mail or attachment that does it either. She has just typed "okay" and that e-mail has taken hours. Problems with the profile or PST/OST?? Any assistance offered would be greatly appreciated.
