I have a user on my Exchange 2000 network that has a major delay when open mail in the inbox. No other user has this issue. The system is a 1.8Ghz processor with 512MB RAM. Plenty of horsepower. There is not an antivirus SW that is scanning the mail, so I don't know what would cause this to just start happening. User has all the latest MS Windows and MS Office patches. Any thoughts? Thanks in advance.
