SBS 2003 running Exchange 2003.
User tried to send out mass email with 6 MB attachment.
Internet connection slows to a crawl. Ping response time is 2000+ ms.
I could see all the messages in the various queues, and tried to delete them from Exchange System Manager. However, when they were all deleted the internet connection did not return to normal speed.
Stopping the SMTP server from within System Manager resolves the Internet speed issue, but when I restart the smtp server, all of the messages re appear in the queues.
I cannot see the messages in the Queues folder on the hard drive; I can only see new messages in there.
How can I resolve this?
Why aren't those messages being deleted when I try to do so from Exchange System Manager?
