I have an exchange server (2003) running about 150 users. Right now it’s behind a DSL broadband line. I know that’s not the right way, and we’re moving soon to a data center, but right now someone just sent out a 7MB attachment to 1,000 (yes, one thousand) people, and our exchange server slowed to a crawl. People aren’t getting their e-mails, and we can barely even log in remotely. We have someone there right now physically accessing the server, but we don’t know how to kill all those e-mails, or in general how to kill a large e-mail that we don’t want being sent out.
Please help ASAP so we can get our server up and running.
