I have Exchange server 2007 running on windows ser ver 2008. It is a single instance, no back end server etc. It is running on a single domain with around 250 user accounts. My users are mainly connected to the Exchange server using http as we have a lot of people in many different location.
It has been running normal for some time but recently I have noticed Outlook takes time to respond to a lot of request. After looking at the server the System memory is being used up by Exchange services leaving less half a GB for system resources.
Has anyone had this problem and resolved it. Thanks for your suggestions.
