Is the Exchange Server installed on a solo server? Have you checked to see if the Exchange Services have any dependencies that no longer exist or are themselves not starting?BP

Exchange is not on a DC? Run ExBPA to see if finds anything. Review Symantec's support site to insure there is no issues with removal of Mail Security and Exchange 2007.MVP Exchange Server

Hello, Could you describe your environment in detail? I suggest you download ExBPA to have a health check for the Exchange Server. It can help you fix some normal issues. If your Exchange Server is installed on Windows 2003 SP2, please install update KB948496 and restart to test the issue. I agree with John, you need to contact Symantec to see if this is a known issue. Thanks, Elvis
