Brandon, Do you have any anti virus software running on that exchange box? Is it hosting your SMTP traffic as well. I m in my intial testing with Exch2k and have seen norton 7.6 do the same thing. What I am developing is that my smtp, filtering and antivirus are going to be on one machine and my exchange users and mailbox are going to be on another.. This is a great solution to help protect yourself from virii etc. Let me know,. Jami L.

After the first day, I defragged the database, and after the second day, I started to cry. Regardless, when STORE.EXE hit it's high's, Outlook users complained about long waits between clicking on an e-mail, and the e-mail to actually come up. The server is only hosting about 40 e-mail accounts, so I can not imagine the users clicking around would cause this intensive CPU use. Any suggestions as to what I can check out? The second day, I ordered 2GB more of RAM for the server (yet to come in), but this has not happened since. Also, after about 1 week of doing the same thing over and over again, I finally have instant messenging up and running. The only problem is, one of my users can not login from their workstation (or any workstation). They get the error message relating to the account not having permission to login as that user. I have verified the settings, and everything is working, except this one account. When I created another account for this user, they still could not login to Messenger, but when I created an account for another user, this worked fine. Are there any logs I can check besides the WWW logs? -----Original Message----- From: dtanner@xxxxxxxxxxx [mailto:dtanner@xxxxxxxxxxx] Sent: Wednesday, April 03, 2002 1:25 PM To: [ExchangeList] Subject: [exchangelist] Missing 'From' http://www.MSExchange.org/ We recently installed Exchange Server 5.5. We have Outlook 98 clients. My problem is that when I send an email to addresses outside of the company, the From information is left off. I've sent email to an account on yahoo.com (and others), and when that account looks at the email, the From is blank. They are able to reply to the email fine, but when they are looking at the list of new emails it appears as possible junk mail because the From is blank. Any ideas? Exchange problem? Outlook problem? ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: blockhart@xxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: jstanek@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
