All of my workstations run Outlook 2007 connect to the Exchange component (2007) of SBS 2008.
One workstation has developed a delay of about 20 minutes in receiving new mail. The user knows it as he also uses an iPhone that's connected to Exchange which hasn't developed the delay.
I've run the Office and Outlook diagnostics but the problem still exists.
Any suggestions or should I just re-install the user's Outlook client?
